Pinching Pain in the Right Side of the Chest

First, an important note: Right-sided chest pain with certain features (shortness of breath, sweating, nausea, dizziness, pain radiating to the jaw or arm, rapid heart rate) requires immediate emergency evaluation - do not wait. If any of those are present, call emergency services now.

Most Common Causes

Pinching or sharp pain specifically on the right side of the chest most often comes from one of these categories:

1. Musculoskeletal (Most Common)

The most frequent cause of a "pinching" quality chest pain, especially in younger or otherwise healthy people.

Costochondritis - inflammation at the junction where ribs meet the breastbone. Classically reproduced by pressing on the chest wall. Responds well to NSAIDs.
Muscle strain - from overuse, coughing, poor posture, or exercise. Aches worsen with movement.
Rib fracture - sharp, focal pain that worsens with breathing or twisting.
Cervical radiculopathy (cervical angina) - nerve root compression at C4-C8 from disc disease can radiate pain into the chest wall. Often associated with neck pain.

Key clue: if pressing on the painful spot reproduces the pain, musculoskeletal cause is very likely. - Frameworks for Internal Medicine, p. 41

2. Pulmonary Causes

Pleurisy - inflammation of the pleural lining surrounding the lung. Pain is typically "pleuritic" - sharp and pinching, made worse with deep breathing, coughing, or sneezing. Can be caused by infection, rheumatologic disease, or medications.
Pneumonia - infection of lung tissue; right-sided pneumonia specifically causes right-sided pleuritic pain, with fever and productive cough.
Pulmonary embolism (PE) - blood clot in the lungs. Can cause sudden-onset right-sided chest pain, especially pleuritic in nature. A medical emergency if suspected.
Pneumothorax - collapsed lung; sudden sharp chest pain with breathlessness.

3. Gastrointestinal Causes

Gallstones / Cholecystitis - the gallbladder sits on the right side under the ribcage. Pain can radiate into the right chest/shoulder, often after fatty meals.
Acid reflux / GERD - burning or pinching sensation that can be felt in the right chest.
Gas and bloating - trapped gas under the diaphragm (especially the hepatic flexure of the colon) can cause right-sided chest discomfort.
Liver pathology - hepatitis or liver capsule distension.

4. Cardiac (Less Common on the Right, But Not to Be Ignored)

While heart attacks classically cause left-sided or central chest pain, research shows that myocardial infarction patients actually report right-sided chest pain twice as often as those with non-cardiac pain (Beunderman et al., 1990). Right-sided cardiac causes include:

Right ventricular ischemia - can produce substernal/right-sided crushing or constricting pain resembling MI.
Pericarditis - inflammation of the heart's sac; sharp pinching pain, often worse lying flat.
Pericardial cyst - rare, usually asymptomatic but can cause chest pain near the right atrium.

5. Other Causes

Herpes zoster (shingles) - a viral nerve infection that causes a burning/pinching pain along one side of the chest, often before any visible rash appears. The pain follows a dermatomal pattern and may appear as vesicular skin blisters later.
Anxiety / Panic disorder - can cause sharp, pinching chest sensations, palpitations, and breathlessness. A diagnosis of exclusion.
Intercostal neuralgia - irritation of the nerves between the ribs; sharp, shooting, or pinching pain that follows the rib line.

When to Seek Emergency Care Immediately

Go to the ER or call emergency services if the pain is:

Sudden and severe
Associated with shortness of breath, sweating, nausea, or dizziness
Radiating to the arm, jaw, or back
Accompanied by rapid or irregular heartbeat
Following a long period of immobility or recent travel (possible PE)

What Helps Narrow It Down

Feature	Points Toward
Pain worsens with pressing the chest wall	Musculoskeletal (costochondritis, strain)
Pain worsens with deep breathing/coughing	Pleurisy, pneumonia, pneumothorax
Pain after fatty meal, under right rib	Gallstones / cholecystitis
Skin rash or blisters along the pain	Shingles (herpes zoster)
Sudden onset with breathlessness	Pulmonary embolism, pneumothorax
Stressful trigger, young person	Anxiety / panic
Fever + productive cough	Pneumonia

A proper evaluation by a doctor - including a physical exam, ECG, and possibly chest X-ray or blood tests - is the only way to confirm the cause. If your pain is new, persistent, or worsening, please get it checked promptly.
