QUICK SUMMARY
✓ Chest pain on the right side is rarely a direct heart attack — the heart sits mostly on the left — but it can still indicate serious conditions requiring urgent care.
✓ The most common causes include muscle strain, pleurisy, pneumonia, pulmonary embolism, GERD, gallbladder disease, and anxiety.
✓ Right side chest pain affects millions annually; musculoskeletal causes account for roughly 28% of emergency room chest pain presentations.
✓ Red-flag symptoms — difficulty breathing, coughing up blood, fever, or sudden severe pain — demand immediate medical attention.
✓ Most benign causes (muscle strain, mild reflux, costochondritis) resolve with rest, anti-inflammatory medication, and postural correction within days to weeks.
✓ A physiotherapy assessment can identify musculoskeletal contributors, guide rehabilitation, and significantly reduce recurrence.
INTRODUCTION
Why Chest Pain on the Right Side Happens — and Why It Matters
Chest pain in any location is alarming. The moment you feel tightness, a sharp stab, or a persistent ache in your chest, your mind races to worst-case scenarios. When the pain is specifically on the right side, most people are surprised to learn that it is less often cardiac and more often related to the lungs, digestive system, or musculoskeletal structures.
That said, 'less often cardiac' does not mean 'never serious.' Certain right-sided chest conditions — a pulmonary embolism, a collapsed lung, or severe pneumonia — are genuine medical emergencies. Understanding the difference between causes that resolve on their own and those that require urgent evaluation could, quite literally, save your life.
This guide walks you through the anatomy of the right chest, every clinically significant cause, how to read your own symptoms, and what modern evidence says about treatment — presented the way a physiotherapist would explain it to a patient in clinic.

ANATOMY OF THE RIGHT CHEST
What Structures Live on the Right Side of the Chest?
Understanding the anatomy is the key to understanding the pain. The right side of the chest contains — and is surrounded by — a remarkably complex set of structures, any of which can generate pain signals:
2. Pleura The pleura is a two-layered membrane that surrounds and protects each lung. The outer layer lines the chest wall (parietal pleura); the inner layer covers the lung surface (visceral pleura). When the right pleura becomes inflamed — a condition called pleuritis — it produces the hallmark sharp, stabbing chest pain that worsens sharply with every breath.
3. Liver and Gallbladder Both organs sit directly beneath the right ribcage, in close anatomical proximity to the lower right chest. When either becomes inflamed or obstructed — through gallstones, hepatitis, or cholecystitis — the pain does not stay localised. It travels upward into the right chest and refers to the right shoulder, making it a frequent cause of misdiagnosed right-sided chest pain.
4. Ribs and Costal Cartilage Twelve pairs of ribs form the protective cage of the chest. The costal cartilage connects each rib to the breastbone (sternum). Any of three distinct problems can generate right-sided chest pain here: a rib fracture (from trauma or osteoporosis), costochondritis (inflammation of the cartilage at the rib-sternum junction), or intercostal muscle strain (injury to the muscles running between the ribs).
5. Oesophagus and Stomach The oesophagus runs through the chest before connecting to the stomach. When stomach acid refluxes upward — as in gastro-oesophageal reflux disease (GERD) — the resulting burning irritation can localise to the right side of the chest, particularly after large meals, when bending forward, or when lying down. GERD is one of the most commonly misidentified causes of chest pain.
6. Right Side of the Heart The right ventricle is responsible for pumping deoxygenated blood from the heart to the lungs via the pulmonary arteries. When the right heart is placed under excessive strain — through pulmonary hypertension, massive pulmonary embolism, or right heart failure — it can generate chest discomfort. However, isolated right-heart pain without an associated pulmonary condition is uncommon and is considered a less frequent cause of right-sided chest pain than the structures listed above.
CAUSES OF CHEST PAIN ON THE RIGHT SIDE
Chest Pain Right Side: All Major Causes Explained
Chest pain on the right side can arise from respiratory, musculoskeletal, digestive, cardiovascular, neurological, or psychological origins. Below are the twelve most clinically significant causes.
1. Muscle Strain (Intercostal or Chest Wall)
The most common single cause of chest pain on the right side in people without underlying disease. Sudden exertion, coughing, awkward movement, or heavy lifting can strain the intercostal muscles between the ribs or the pectoral and serratus muscles of the chest wall. Pain is typically localised, tender to touch, and worsens with specific movements or deep breaths. It generally resolves within days to two weeks with rest, ice, and anti-inflammatory medication.
2. Pleurisy (Pleuritis)
Inflammation of the pleural membrane surrounding the right lung. The hallmark is sharp, stabbing chest pain that intensifies with inhalation or coughing, often accompanied by shoulder pain. Pleurisy is most commonly caused by viral infection, but can also be bacterial, or secondary to pulmonary embolism, autoimmune conditions, or cancer. Most cases resolve with treatment of the underlying cause.
3. Pulmonary Embolism (PE)
A blood clot — typically originating in a deep leg vein — travels to and blocks a pulmonary artery in the right lung. Pulmonary embolism is a medical emergency. It presents with sudden, sharp right-sided chest pain that worsens with inhalation, accompanied by shortness of breath, rapid heart rate, and sometimes coughing up blood. If PE is suspected, call emergency services immediately. Untreated, it can be fatal.
4. Pneumonia
An infection of the right lung causes pleuritic chest pain (worse on breathing), fever, chills, productive cough with coloured mucus, and fatigue. Right-lower-lobe pneumonia is particularly common and can sometimes mimic abdominal pain or gallbladder problems due to its lower chest location. Bacterial pneumonia is treated with antibiotics; viral pneumonia is managed supportively.
5. Gallbladder Disease (Biliary Colic / Cholecystitis)
The gallbladder sits directly beneath the right ribcage. Gallstones obstructing the bile duct produce severe, cramping pain in the upper right abdomen that classically radiates up into the right chest and right shoulder. Pain typically peaks 30-90 minutes after a fatty meal. Cholecystitis (gallbladder inflammation) adds fever and prolonged tenderness. Gallbladder disease is one of the most frequently missed non-cardiac causes of right chest discomfort.
6. Costochondritis
Inflammation where the ribs join the cartilage of the sternum (breastbone). Although classically central or left-sided, costochondritis frequently presents on the right side, producing sharp pain that worsens with pressure on the chest wall, deep breathing, or physical activity. It is benign and self-limiting, usually resolving over weeks to months. NSAIDs and physiotherapy are first-line management.
7. Pneumothorax (Collapsed Lung)
Air entering the pleural space causes all or part of the lung to collapse. It presents as sudden, severe right-sided chest pain with acute shortness of breath. Spontaneous pneumothorax most often affects tall, young, thin males; it can also follow trauma or lung disease. A tension pneumothorax — in which pressure builds and compresses the heart — is immediately life-threatening and requires emergency decompression.
8. GERD and Acid Reflux
Gastro-oesophageal reflux disease causes stomach acid to flow back into the oesophagus, producing burning chest pain (heartburn) that can radiate to the right side, particularly after large meals, when lying flat, or when sleeping. GERD-related chest pain is often confused with cardiac pain. Lifestyle modifications, dietary changes, elevation of the head during sleep, and medication (proton pump inhibitors) are highly effective.
9. Liver Conditions
Hepatitis (liver inflammation), liver abscess, and in some cases liver cancer can produce right-sided chest and upper abdominal pain. The liver is immediately below the right ribs, and any significant swelling or inflammation generates referred pain upward. Accompanying features may include jaundice, dark urine, fatigue, and abdominal distension.
10. Anxiety and Panic Attacks
Anxiety triggers genuine physical chest pain through muscle tension, hyperventilation, and the physiological stress response. Panic attacks can closely mimic cardiac or pulmonary emergencies, with chest tightness, shortness of breath, rapid heart rate, and a sense of impending doom. Pain typically resolves within 20 minutes. A cardiac cause must always be excluded first before attributing pain to anxiety.
11. Shingles (Herpes Zoster)
Reactivation of the chickenpox virus along a thoracic nerve root produces burning, shooting pain on one side of the chest, days before any rash appears. This can be deeply confusing diagnostically. When the characteristic stripe-like blistering rash emerges (following a dermatome), the diagnosis becomes clear. Early antiviral treatment significantly reduces the risk of long-term post-herpetic neuralgia.
12. Rib Fracture
A fractured rib causes exquisite, localised chest pain that dramatically worsens with breathing, coughing, or any trunk movement. It follows trauma, but in older patients or those with osteoporosis, it can occur with minimal force (even a sneeze). Multiple rib fractures can compromise breathing mechanics. Pain management and breathing physiotherapy are the primary treatment approaches.
SIGNS & SYMPTOMS OF RIGHT SIDE CHEST PAIN
Recognising Right-Sided Chest Pain: What to Look For
The character of the pain — its quality, timing, triggers, and accompanying features — tells you a great deal about its origin. Here is how to read your symptoms:
MUSCULOSKELETAL / BENIGN
– Pain reproducible by pressing on the chest wall
– Worsens with specific movements or twisting
– Improves with rest
– Tenderness at a precise point on the ribs
– Onset after exertion, coughing, or awkward posture
– Mild to moderate severity, does not radiate
RESPIRATORY / SERIOUS
– Sharp pain that worsens with every breath
– Shortness of breath at rest
– Fever, chills, or productive cough
– Coughing up blood (haemoptysis)
– Pain after long travel or immobility (PE)
– Sudden onset with rapid deterioration
DIGESTIVE / REFERRED
– Pain after fatty meals; worsens lying down
– Burning sensation rising from the stomach
– Radiates to the right shoulder blade
– Accompanied by nausea or bloating
– Jaundice or dark-coloured urine (liver)
– Improves after antacids or sitting up
NEUROLOGICAL / OTHER
– Burning or shooting pain along a skin stripe
– Hypersensitivity of the skin (shingles)
– Blistering rash following the ribs
– Heart racing, sweating, sense of doom (panic)
– Chest pain triggered by emotional stress
– Onset linked to illness, chickenpox history
Seek Emergency Care Immediately
Several presentations require immediate emergency medical attention without delay. Sudden severe chest pain accompanied by shortness of breath may indicate a pulmonary embolism or pneumothorax and must be treated as an emergency. Chest pain that radiates to the jaw, left arm, or back alongside sweating and nausea raises strong concern for a heart attack and demands urgent care. Coughing up blood in conjunction with chest pain is likewise a red flag requiring immediate assessment.
Any rapid deterioration in breathing over the course of minutes warrants emergency attendance, as does chest pain arising after a recent long-haul flight, extended car journey, or surgical procedure, all of which carry a significantly elevated risk of pulmonary embolism. A fever exceeding 38.5 degrees Celsius, combined with chest pain and a productive cough, may indicate severe pneumonia and should not be managed at home. Finally, visible asymmetry of the chest or deviation of the trachea from the midline are signs of a potential tension pneumothorax — a life-threatening emergency requiring immediate intervention.

CLINICAL PEARLS
Physiotherapist Insights: What Clinics Know That Patients Often Don't
Clinical Pearl #1: The Breathing Test
If pressing on a specific rib or spot on the chest wall reproduces the pain precisely, the cause is almost certainly musculoskeletal rather than cardiac or pulmonary. Conditions such as pleurisy, pulmonary embolism, and pneumonia do not reproduce pain on chest wall palpation. This single clinical test is therefore remarkably powerful, significantly narrowing the diagnosis within a matter of seconds.
Clinical Pearl #2: Gallbladder Pain Is the Great Imitator
Acute gallbladder pain, or biliary colic, is consistently mistaken for right-sided heart or lung problems. The key distinguishing features are pain triggered by fatty food, peaking between 30 and 90 minutes after eating, radiating to the right shoulder blade rather than the jaw or left arm, and accompanied by nausea. Where these features are present, an abdominal ultrasound — rather than a chest X-ray — is the more appropriate first investigation.
Clinical Pearl #3: Post-COVID Chest Pain Is Underrecognised
A significant number of patients who experienced COVID-19, including those with mild cases, develop ongoing right-sided or bilateral chest pain months after infection. The underlying causes can include post-viral pleuritis, musculoskeletal sequelae resulting from prolonged coughing, and post-COVID pulmonary fibrosis. In any patient presenting with a history of COVID-19 and new chest pain, this differential must be actively and deliberately considered rather than overlooked.
DIAGNOSIS OF RIGHT SIDE CHEST PAIN
How Is Right-Sided Chest Pain Diagnosed?
An accurate diagnosis requires a structured clinical approach. The following table outlines the most common investigations your doctor or specialist may use:
A Chest X-Ray is typically the first-line imaging used for most chest pain presentations, capable of detecting pneumonia, pneumothorax, rib fractures, and pleural effusion.
CT Pulmonary Angiography (CTPA) is the gold standard investigation for suspected pulmonary embolism, identifying blood clots within the lung arteries and is treated as an urgent investigation in such cases.
An ECG (Electrocardiogram) is used to detect cardiac arrhythmias, right heart strain, and ischaemia, and is routinely performed to rule out cardiac causes even when pain is right-sided.
Blood Tests — including D-dimer, Troponin, LFTs, and FBC — help detect clot markers, cardiac damage, liver dysfunction, and signs of infection, guiding clinical urgency and narrowing the list of differentials.
Abdominal Ultrasound is employed when a biliary or hepatic cause is suspected, as it can identify gallstones, cholecystitis, and other liver pathology.
Spirometry or Peak Flow testing is used in patients presenting with wheeze, dyspnoea, or chronic cough to assess for underlying conditions such as COPD, asthma, or restrictive lung disease.
Finally, a Physiotherapy Assessment is undertaken once serious causes have been excluded, focusing on musculoskeletal contributors such as muscle strain, costochondritis, and postural factors.
TREATMENT FOR CHEST PAIN ON THE RIGHT SIDE
Treatment for Chest Pain Right Side: A Cause-by-Cause Guide
Treatment is entirely determined by cause. There is no single remedy for right-sided chest pain — matching the intervention to the diagnosis is what produces results.
Medication plays a central role in many causes of right-sided chest pain. NSAIDs such as ibuprofen and naproxen are used to manage muscle pain and costochondritis, while antibiotics are prescribed for bacterial pneumonia. Blood thinners, including heparin and warfarin, are used in the management of pulmonary embolism, proton pump inhibitors are indicated for GERD, and antivirals are prescribed in cases of shingles.
Physiotherapy is targeted toward musculoskeletal causes and encompasses a range of approaches, including postural correction, thoracic mobility exercises, breathing retraining, muscle release techniques, and progressive loading strategies designed to prevent recurrence.
Rest and Self-Care measures are important in the early stages of recovery. Ice is recommended for acute muscle injuries during the first 48 to 72 hours, followed by the gentle application of warmth. For GERD, small and upright meals are advised alongside avoidance of known triggers and sleep position adjustments, such as elevating the head and avoiding lying on the right side.
Medical Procedures may be necessary in more serious cases. These include insertion of a chest drain for pneumothorax or pleural effusion, surgical removal of the gallbladder for recurrent gallstones, clot-dissolving thrombolysis therapy for massive pulmonary embolism, and hospitalisation for severe pneumonia.
Psychological Support is an important component of care where chest pain has a psychological basis. Cognitive behavioural therapy and breathing techniques are used for panic-related presentations, alongside mindfulness-based stress reduction and treatment of any underlying anxiety or depression.
Lifestyle Modifications form a key part of long-term management. These include dietary changes for GERD and gallbladder disease, smoking cessation to reduce the risk of lung disease, a graduated return to activity following musculoskeletal injury, and the use of compression stockings alongside adequate hydration for pulmonary embolism prevention.
PHYSIOTHERAPY FOR CHEST PAIN
How Physiotherapy Addresses Chest Pain on the right side
When serious pathology has been excluded, physiotherapy is highly effective for the large proportion of right-sided chest pain that is musculoskeletal or postural in origin. A physiotherapy assessment identifies which structures are involved, addresses contributing factors such as poor posture, thoracic stiffness, or respiratory dysfunction, and designs a progressive rehabilitation plan.
Key Physiotherapy Interventions
Thoracic Spine Mobilisation: Stiffness in the mid-back (thoracic spine) is a frequently overlooked contributor to both rib and chest wall pain. Manual mobilisation and extension exercises restore thoracic range of motion and reduce compensatory loading on the costal joints.
Intercostal Muscle Release: Trigger point therapy and soft tissue release to the intercostal muscles can rapidly reduce localised right-sided chest pain in patients with muscle strain or post-cough injury.
Breathing Retraining: Dysfunctional breathing patterns — particularly upper-chest breathing and breath-holding — significantly worsen chest wall pain and perpetuate anxiety-related chest tightness. Diaphragmatic breathing retraining is a foundational physiotherapy intervention.
Postural Correction: Sustained forward-head posture and thoracic kyphosis compress the anterior chest and overload the right costochondral joints. Ergonomic assessment and postural strengthening (serratus anterior, mid-trapezius, rhomboids) directly address this.
Graded Return to Activity: Following rib fracture, muscle strain, or post-PE rehabilitation, physiotherapy guides safe, progressive return to daily activities, work, and exercise — reducing both recurrence and fear-avoidant behaviour.
Clinical Pearl #4: Breathing Mechanics After Rib Injury
Patients with rib fractures instinctively adopt shallow breathing patterns to avoid pain. However, this natural protective response carries significant clinical risk, increasing the likelihood of retained secretions, atelectasis — partial collapse of the lung — and the subsequent development of pneumonia. For this reason, incentive spirometry and controlled deep breathing exercises, guided by a physiotherapist, are considered critical interventions in the first 48 to 72 hours following a rib injury. These measures are not optional adjuncts but essential components of early management.
EVIDENCE BASE
What the Research Tells Us
The evidence on right-sided chest pain is clear on several key points:
Musculoskeletal causes are dramatically underestimated. Research across multiple emergency department studies consistently finds that chest wall pain — muscle strain, costochondritis, and rib injury — accounts for approximately 28% of chest pain presentations, making it the single most common non-cardiac cause in younger, active populations.
Pulmonary embolism is the most frequently missed serious cause. A systematic review in the Annals of Emergency Medicine found PE is missed on first presentation in up to 29% of confirmed cases. Any right-sided chest pain with unexplained shortness of breath in a patient with risk factors should be treated as PE until proven otherwise.
GERD is vastly undertreated as a cause of chest pain. Studies estimate that 10-30% of patients presenting to cardiology with chest pain have GERD as the primary cause, yet fewer than half have received a trial of anti-reflux therapy before referral.
Physiotherapy produces comparable outcomes to medication for musculoskeletal chest wall pain. A 2024 systematic review (Frontiers in Medicine) confirmed that physiotherapy-led interventions — postural correction, manual therapy, and breathing retraining — achieve equivalent or superior outcomes to NSAIDs alone for costochondritis and intercostal muscle pain, with lower recurrence rates.

FREQUENTLY ASKED QUESTIONS
Chest Pain Right Side — Your Questions Answered
Q: Is right-sided chest pain always serious?
A: No. The majority of right-sided chest pain cases are caused by benign musculoskeletal conditions (muscle strain, costochondritis, rib injury) or digestive issues (GERD, gallbladder) that resolve without intervention or with simple treatment. However, some causes — pulmonary embolism, pneumothorax, pneumonia — are medical emergencies. Any chest pain that is sudden, severe, accompanied by breathing difficulty, or not clearly explained by a benign cause should be medically evaluated promptly.
Q: Can chest pain on the r be a heart attack?
A: Classic heart attacks (left ventricular myocardial infarction) typically cause central or left-sided chest pain. However, right-sided heart involvement — right ventricular infarction, or rarely, referred pain from atypical presentations — can occasionally cause right-sided discomfort. Never dismiss chest pain as non-cardiac purely based on its side. If you are in doubt, seek emergency evaluation: an ECG and troponin blood test will quickly clarify.
Q: Why does my right-sided chest hurt more when I breathe in?
A: Pain that worsens sharply on inhalation is called 'pleuritic' pain and is a hallmark of pleural irritation. The most common causes are pleurisy (pleural membrane inflammation), pulmonary embolism, pneumonia, and pneumothorax. Rib fractures and severe muscle strain can also produce breath-related pain, but through mechanical rather than pleural mechanisms. Any new-onset pleuritic chest pain warrants medical assessment to rule out serious lung pathology.
Q: Can anxiety really cause physical chest pain on the right side?
A: Yes, absolutely. Anxiety and panic attacks generate genuine, physically felt chest pain through multiple mechanisms: hyperventilation (raising CO2, causing chest tightness), sustained muscle tension in the chest wall, and the physiological activation of the stress response. The pain is real — it is not imagined. However, a cardiac or pulmonary cause must always be excluded before attributing chest pain to anxiety. Once excluded, cognitive behavioural therapy, breathing retraining, and anxiety management are highly effective.
Q: How long does right-sided chest pain from a muscle strain last?
A: Many people experiencing chest pain on the right side from a muscle strain recover fully within 3-7 days with rest and anti-inflammatory medication. Moderate strains may take 2-4 weeks. Severe strains or rib injuries can take 6-12 weeks for full resolution. Physiotherapy can accelerate recovery by reducing muscle guarding, restoring movement, and preventing secondary postural problems from pain-related breath-holding.
Q: What exercises help with right-sided chest pain from a musculoskeletal cause?
A: Once serious causes are excluded, targeted physiotherapy exercises are highly effective. Key exercises include: thoracic extension over a foam roller (to mobilise mid-back stiffness), intercostal stretching (arm raised overhead, gentle side-bend away from the painful side), diaphragmatic breathing (to reduce chest-wall guarding and improve lung ventilation), and progressive postural strengthening once acute pain settles. Always have a physiotherapist guide your programme initially.
Q: Should I go to the emergency room for right-sided chest pain?
A: Yes, if any of the following are present: sudden severe pain, shortness of breath, pain worsening on every breath, coughing up blood, high fever, rapid heart rate, pain after prolonged travel or surgery, or if the pain is new and you cannot identify a clear benign cause. If the pain is mild, clearly reproduces on pressing the chest wall, and you have had similar pain before from a known musculoskeletal cause, it may be appropriate to monitor and see your GP the same day. When in doubt, always seek assessment.
