Chest Muscle Strain: Symptoms, Recovery and Warning Signs

Quick answer

Reproducible pain on movement; rule out the heart first when in doubt

A strain of the pectoral or intercostal (between the ribs) muscles typically follows twisting, heavy lifting, a hard cough or a workout, and causes localised pain that worsens with movement, deep breaths, coughing or pressing on the area. Mild to moderate strains heal in 2–6 weeks. Treatment includes brief relative rest, pain relief, heat or cold for comfort and gradual return to movement and stretching. Because heart attack, pulmonary embolism and other conditions can cause chest pain, any chest pain that is unexplained, pressure-like, or accompanied by shortness of breath, sweating or spreading to the arm or jaw requires emergency care.

Important. Chest pain with pressure or tightness, spreading to the arm, neck or jaw, with shortness of breath, sweating, nausea or fainting, or sudden severe breathlessness, call emergency services immediately. Do not assume it is a muscle strain.

What is a chest muscle strain?

The chest wall includes the pectoralis major and minor, the intercostal muscles between the ribs, serratus anterior and the muscles of the upper abdomen and back. A strain is an overstretch or small tear in any of these. It can happen during weightlifting (bench press, push-ups), racket sports, rowing, sudden twisting, heavy lifting, falls or prolonged coughing.

Symptoms

Sharp or aching pain in the chest wall, often localised to one spot.
Pain that gets worse with movement, deep breathing, coughing, sneezing, twisting or raising the arm.
Tenderness when pressing on the painful area, which reproduces the pain.
Swelling or bruising in pectoral injuries; a bulge or defect with severe tears.
Muscle spasm or tightness; weakness in pushing or lifting.
No shortness of breath at rest, sweating or other systemic symptoms.

Chest pain: rule out serious causes first

Muscle pain is common, but chest pain has many other causes, some life-threatening: heart attack and angina, pulmonary embolism, aortic dissection, pneumothorax, pneumonia and pericarditis. Features that should prompt emergency assessment are chest pressure or tightness, pain spreading to the arm, jaw or back, pain with exertion, breathlessness, sweating, nausea, dizziness or palpitations, particularly in people with risk factors (age, smoking, diabetes, high blood pressure, cholesterol, family history). Pain that is sharp, localised, reproduced by pressing or moving is more likely musculoskeletal, but only a clinician can be sure.

Other causes of chest wall pain

Costochondritis: inflammation of the cartilage where ribs meet the breastbone; tender to pressure.
Rib injury or fracture, from trauma or heavy coughing.
Slipped or intercostal nerve irritation, shingles (burning pain with a rash).
Muscle strain from weightlifting or twisting.
Reflux and other digestive problems.
Anxiety and panic, which can cause chest tightness.
Lung or pleural conditions, causing pain on deep breathing.

Self-care for a chest wall strain

Relative rest from painful activities for several days; avoid heavy lifting and pushing.
Use paracetamol or, if suitable, a short course of ibuprofen; topical anti-inflammatory gels can help.
Apply heat or cold for comfort for 15–20 minutes at a time.
Take regular, gentle deep breaths and coughing exercises with a hand or pillow to support the chest; avoid shallow breathing, which can lead to chest infections.
Keep moving gently and do not immobilise the area.
Sleep in a comfortable, slightly upright position.

Exercises to restore movement

Gentle pendulum and shoulder circles once pain allows.
Doorway pectoral stretch for 20–30 seconds, to mild tension only.
Thoracic rotation and cat–camel exercises.
Light resistance with bands for the chest and upper back when comfortable.
Gradual return to pushing exercises such as wall and incline push-ups.
Return to full lifting when pain-free, with full range and strength.

How long does it take to heal?

Mild strains improve within 1–2 weeks; moderate within 4–6 weeks. Pectoral muscle tears from heavy lifting can take months, and complete ruptures may need surgery. Rib-related pain can last 6–8 weeks. Return gradually and avoid heavy lifting until you have full pain-free movement.

Prevention

Warm up before lifting, with dynamic upper-body movements.
Use appropriate loads and good technique, particularly in bench press and push-ups.
Increase training intensity gradually.
Strengthen the whole upper body and trunk, including the upper back.
Avoid very heavy lifting without a spotter.
Manage persistent cough and seek treatment for chest infections.

When to see a doctor

Any chest pain with warning features (see above): call emergency services.
Severe pain after trauma, suspected rib fracture, or difficulty breathing.
A bulge, gap or large bruise in the chest or armpit after lifting.
Pain lasting more than 2–3 weeks or worsening.
Fever, cough with phlegm or a rash with burning pain.
Recurrent unexplained chest pain.

Three common situations

Sharp pain in the side of the chest after a hard workout, worse with deep breaths and pressing: likely a muscle strain; self-care and check with a clinician if unsure.

Pain after weeks of heavy coughing: intercostal strain or a rib injury is possible; support the chest and seek advice.

Pressure in the chest with exertion and sweating: call emergency services.

Key points to remember

Chest wall strains cause localised pain that is worse with movement, and improve with relative rest and gradual activity. Never ignore chest pain with warning features: seek emergency care. If in doubt, get checked. Our physical therapy team can help you recover and return safely to activity.

Questions about chest muscle strains

These answers are general information and do not replace an examination or individual medical advice.

How do I know if chest pain is muscular?

Muscular pain is usually sharp, localised, and reproduced by pressing or moving, but only a clinician can be sure; seek urgent care if there are warning signs.

How long does a pulled chest muscle take to heal?

Mild strains 1–2 weeks; moderate 4–6 weeks; severe tears longer.

Can I exercise with a chest strain?

Gentle movement is fine; avoid heavy lifting and pushing until pain-free.

Is heat or ice better?

Either, for comfort; neither speeds healing.

What painkillers can I take?

Paracetamol, or ibuprofen if suitable for you; topical gels can help.

When is chest pain an emergency?

When it feels like pressure or tightness, spreads to the arm or jaw, or comes with breathlessness, sweating or fainting.
