Shoulder Bursitis (Subacromial Bursitis)

Inflammation of the bursa, the small fluid-filled sac that cushions and reduces friction between the shoulder bones, tendons, and muscles.

Symptoms

• Dull ache or sharp pain on the outside or top of the shoulder
• Increased pain when lifting the arm overhead or reaching backward
• Discomfort when lying on the affected side
• Joint stiffness and localized tenderness

Causes 

Repetitive overhead motions, direct trauma or falls, and mechanical impingement from bone spurs.

Risk Factors

• Participation in overhead sports (baseball, swimming, tennis)
• Manual occupations (painting, carpentry, construction)
• Poor posture and natural age-related joint degeneration

Diagnosis 

A clinical physical exam assessing range of motion and strength, alongside X-rays or MRI imaging to evaluate joint anatomy and rule out rotator cuff tears.

Treatment

• Conservative: Rest, ice therapy, NSAIDs, targeted physical therapy, and corticosteroid injections.
• Surgical: Minimally invasive arthroscopic bursectomy for chronic cases unresponsive to non-surgical care.
