Shoulder Bursitis: Symptoms

Shoulder bursitis causes pain in the front or side of the shoulder, difficulty lifting the arm overhead, and pain that the American Academy of Orthopaedic Surgeons describes as typically at its worst at night — bad enough, in more severe cases, to interfere with sleep.

Why the pain sits where it does

Between the rotator cuff and the bone on top of the shoulder blade there is a lubricating sac, the bursa, that lets the tendons glide. When that space is repeatedly compressed the bursa becomes inflamed and the tendons irritated, and the pain concentrates at the front and side of the joint rather than deep inside it. Raising the arm narrows the space, which is why overhead movement is the motion that hurts.

Signs to look for

• Pain in the front or side of the shoulder, not usually across the back.
• Difficulty lifting the arm overhead, including reaching behind the back.
• Pain at night, at its worst when lying down — the most distinctive feature.
• Tenderness over the top and outer part of the joint.

Bursitis and tendinitis in the same shoulder

The AAOS does not treat these as two separate conditions here: shoulder bursitis and rotator cuff tendinitis are covered together, because the bursa sits directly on the tendons and the same impingement irritates both. Expect overlapping symptoms rather than a clean distinction. The general picture across joints is in bursitis symptoms, and the contrast with a superficial bursa — where swelling leads and pain lags — is clearest in elbow bursitis: symptoms.

What raises the risk

Overhead sports such as swimming, tennis and baseball; occupations involving repetitive lifting or overhead work, with construction and painting named specifically; and minor injuries to the joint.

How it is treated

The AAOS path starts with rest and activity modification, anti-inflammatory medicines like ibuprofen, aspirin or naproxen, and physical therapy aimed at restoring motion and then strengthening. A steroid injection into the bursa is the next step when that is not enough. Surgery — bursectomy, or acromioplasty to create more room in the joint — is reserved for cases that do not respond. Most patients improve without surgery, but the AAOS is explicit that full recovery may take several weeks to months.

When to see an orthopedist

Seek evaluation if the pain persists, limits day-to-day use of the arm, or wakes you regularly at night. Intense redness and warmth over the joint, or fever, point toward infection rather than simple bursitis and deserve faster attention.
