When the bursa becomes irritated, it fills with excess fluid, becomes painful, and may swell. In the chest, this pain is often felt on the front of the rib cage, near the breastbone or under the shoulder blade, and can mimic heart‑related or lung‑related complaints, which is why proper evaluation is essential.

Although “chest bursitis” is not as frequently diagnosed as shoulder or hip bursitis, it does occur—especially in people who perform repetitive upper‑body motions, lift heavy objects, or have underlying inflammatory conditions.

Common Causes

The inflammation can be triggered by a variety of mechanical, infectious, or systemic factors. Below are the most frequent contributors:

• Repetitive overhead activity: Weight‑lifting, painting, carpentry, or sports such as swimming and volleyball.
• Direct trauma: A blow to the chest wall (e.g., a fall, car accident, or sports collision).
• Strain from heavy lifting: Carrying or moving heavy boxes, furniture, or equipment.
• Postural strain: Prolonged hunching or rounded‑shoulder posture that compresses the chest‑wall bursa.
• Infection (septic bursitis): Bacteria such as Staphylococcus aureus entering the bursa through a skin break.
• Inflammatory arthritides: Rheumatoid arthritis, psoriatic arthritis, or gout can involve bursae.
• Degenerative changes: Osteoarthritis of the ribs or sternoclavicular joint can irritate adjacent bursae.
• Systemic medications: Long‑term corticosteroid use can thin the bursal wall, making it more susceptible to irritation.
• Obesity or rapid weight gain: Increases mechanical stress on the chest wall.
• Improper ergonomics: Working at a desk with a poorly positioned monitor or keyboard can lead to chronic shoulder‑chest strain.

Associated Symptoms

Chest bursitis rarely occurs in isolation. Patients often report a cluster of related findings, including:

• Localized pain that worsens with deep breathing, coughing, or arm movement.
• Sensitivity to touch (tenderness) over the affected rib or sternum.
• Visible or palpable swelling or a fluid‑filled “bump.”
• Stiffness or reduced range of motion in the shoulder or upper arm.
• Occasional “crepitus” – a crackling sensation when moving the shoulder.
• Redness or warmth over the bursa if infection is present.
• Low‑grade fever (usually < 101°F) in septic cases.
• Radiating pain to the back, neck, or down the arm, often mistaken for nerve‑root irritation.

When to See a Doctor

Most cases of chest bursitis improve with self‑care, but you should seek professional evaluation promptly if you experience any of the following:

• Severe, sudden chest pain that does not improve with rest.
• Pain that radiates to the jaw, left arm, or back and is accompanied by shortness of breath (possible heart attack).
• Fever, chills, or rapid heart rate, especially with swelling—signs of infection.
• Progressive weakness or numbness in the arm or hand.
• Persistent pain lasting more than 2‑3 weeks despite home measures.
• Visible skin breakdown, draining fluid, or foul‑smelling discharge.

Early evaluation helps rule out life‑threatening conditions such as myocardial infarction, pulmonary embolism, or pneumonia.

Diagnosis

Doctors use a combination of history, physical examination, and imaging or laboratory studies to confirm chest bursitis.

1. Medical History & Physical Exam

• Ask about activity level, recent injuries, and systemic illnesses (e.g., rheumatoid arthritis).
• Inspect the chest wall for swelling, redness, or bruising.
• Palpate the area gently to locate tenderness and assess for fluctuance (fluid).
• Assess shoulder range of motion and look for pain with specific movements (e.g., arm elevation).

2. Imaging Studies

• Ultrasound: Quick, bedside tool to detect fluid collection within the bursa.
• Magnetic Resonance Imaging (MRI): Provides detailed images of soft tissues, helps differentiate bursitis from tendon tear or tumor.
• X‑ray: Mostly to rule out rib fracture or osteoarthritis; not diagnostic for bursitis.

3. Laboratory Tests

• Complete blood count (CBC): Elevated white blood cells suggest infection.
• Erythrocyte sedimentation rate (ESR) / C‑reactive protein (CRP): Markers of inflammation.
• Aspirate of bursal fluid: In septic cases, fluid is sent for Gram stain and culture.

Treatment Options

Management is typically stepwise, beginning with conservative measures and progressing to medical or procedural interventions when needed.

1. Home & Lifestyle Care

• Rest: Avoid activities that provoke pain for 48‑72 hours.
• Ice: Apply a cold pack (15 min on, 15 min off) for the first 24‑48 hours to reduce swelling.
• Heat: After the acute phase, gentle warm compresses can relax surrounding muscles.
• Compression: Elastic bandage may provide mild support, but avoid excessive pressure that restricts breathing.
• Over‑the‑counter pain relievers: NSAIDs such as ibuprofen 400‑600 mg every 6‑8 h (unless contraindicated) can alleviate pain and inflammation.
• Gentle stretching: Pendulum swings and doorway stretches improve shoulder mobility without aggravating the bursa.

2. Prescription Medications

• Stronger NSAIDs: Naproxen or diclofenac may be prescribed for persistent inflammation.
• Corticosteroid injection: One‑time intra‑bursal injection of a glucocorticoid (e.g., methylprednisolone) provides rapid relief for many patients.
• Antibiotics: If septic bursitis is confirmed, a 10‑14‑day course of appropriate oral or IV antibiotics (often a first‑generation cephalosporin) is required.

3. Physical Therapy

Physical therapists design programs that focus on:

• Postural correction (scapular stabilisation, thoracic extension).
• Strengthening of the rotator cuff and scapular retractors.
• Gradual return to activity using a “pain‑free” progression.

4. Procedural Options

• Aspiration: Removal of excess fluid can both relieve pressure and allow laboratory analysis.
• Arthroscopic bursectomy: In rare refractory cases, surgical removal of the inflamed bursa may be performed.

5. Managing Underlying Conditions

If the bursitis is secondary to rheumatoid arthritis, gout, or another systemic disease, appropriate disease‑modifying therapy (DMARDs, colchicine, urate‑lowering agents) is essential to prevent recurrence.

Prevention Tips

While not all cases are preventable, the following strategies can substantially lower risk:

• Maintain good posture: Keep shoulders back, monitor at eye level, and avoid slouching while sitting.
• Ergonomic workstations: Use adjustable chairs and keyboards; consider a standing desk if you sit for long periods.
• Warm‑up before activity: Gentle shoulder circles and arm swings prepare the bursa for motion.
• Strengthen shoulder girdle: Regular resistance training for the rotator cuff and serratus anterior reduces strain.
• Use proper lifting techniques: Bend at the knees, keep the load close to the body, and avoid twisting.
• Gradual progression: Increase weight or repetitions slowly to give tissues time to adapt.
• Stay hydrated and maintain a healthy weight: Reduces overall joint stress.
• Promptly treat skin cuts or abrasions: Reduces the chance of bacteria reaching a bursa.

Emergency Warning Signs

If you notice any of the following, seek emergency medical care (call 911 or go to the nearest emergency department):

• Sudden, crushing chest pain accompanied by shortness of breath, nausea, or sweating.
• Severe pain that spreads to the left arm, jaw, or upper back.
• High fever (> 101°F) with rapidly enlarging, red, and hot swelling.
• Rapid heartbeat ( > 120 bpm ), low blood pressure, or feeling faint.
• Difficulty breathing or a feeling of tightness in the chest.
• Sudden weakness, numbness, or paralysis in an arm or hand.

Key Take‑aways

• Chest bursitis is inflammation of a chest‑wall bursa, often caused by repetitive motion, trauma, or infection.
• Symptoms include localized pain, swelling, and tenderness that worsen with arm movement or deep breathing.
• Most cases respond to rest, ice, NSAIDs, and physical therapy; infections require antibiotics.
• Prompt evaluation is essential to rule out heart, lung, or septic emergencies.
• Prevention focuses on posture, proper ergonomics, gradual activity progression, and treating skin injuries promptly.
