ShoulderSubacromial Bursitis
Subacromial bursitis is inflammation of the bursa — a fluid-filled sac — that sits between the rotator cuff and the underside of the acromion. It is one of the most common causes of shoulder pain and is frequently associated with rotator cuff tendinopathy and impingement syndrome.
⏱️
Typical Recovery Time
4–8 weeks with conservative treatment and injection
Symptoms
- •Aching pain at the outer shoulder and upper arm
- •Painful arc of motion between 60–120 degrees
- •Pain with reaching overhead or behind the back
- •Night pain, especially sleeping on the affected side
- •Tenderness over the lateral shoulder
Common Causes
- •Repetitive overhead activity
- •Acromial bone spur decreasing subacromial space
- •Rotator cuff weakness causing upward humeral migration
- •Direct trauma to the shoulder
- •Poor posture and scapular mechanics
Treatment Options
1Relative rest and activity modification
2NSAIDs and ice
3Physical therapy for impingement correction
4Subacromial corticosteroid injection (highly effective)
5Arthroscopic bursectomy for chronic refractory cases
When to See a Doctor
See a provider if shoulder pain persists more than 4–6 weeks or significantly limits overhead function.
Frequently Asked Questions
What is subacromial bursitis?
Subacromial bursitis is inflammation of the fluid-filled sac that helps reduce friction in the shoulder. When irritated, it can cause pain with movement. It often occurs along with rotator cuff problems.
What causes subacromial bursitis?
It is commonly caused by repetitive overhead activity, overuse, or shoulder impingement. Poor mechanics and muscle imbalance can contribute. Injury or sudden increases in activity may also trigger symptoms.
What are the symptoms?
Symptoms include shoulder pain, especially with lifting or reaching overhead. Pain may worsen at night or when lying on the shoulder. Some people notice stiffness or limited motion.
How is it treated?
Treatment includes rest, physical therapy, and anti-inflammatory medications. Strengthening and improving shoulder mechanics are important. Injections may be used if symptoms do not improve.
When can I return to activity?
Most patients improve over several weeks with proper treatment. Return to activity depends on pain-free movement and strength. Gradual progression helps prevent recurrence.
