Bursitis is inflammation or swelling of one or more fluid filled sacs known as bursae. These sacs are lined with a synovial membrane that produce a lubricating synovial fluid. With bursitis there may be difficulty moving, tenderness, and pain in the area affected. With bursitis of gradual onset pain may be absent. Complications may include septic bursitis.

Causes of bursitis include overuse, infection, trauma, and inflammatory disorders. There are more than 150 bursae in the human body. The most commonly affected are the prepatellar, olecranon, trochanteric, and retrocalcaneal. The bursae are at locations where muscles, tendons, and other tissues slide across prominent areas of bone. Normally they function to improve movement between tissues. Diagnosis is generally based on symptoms and examination and may be supported by additional testing. Other causes of similar symptoms include arthritis, fractures, tendinitis, and nerve problems.

Treatment is typically with rest, ice, compression, and nonsteroidal anti-inflammatory medications (NSAIDs). Steroid injections or surgery may less commonly be used. Evidence for steroid injections in long term bursitis; however, is lacking as of 2020. Bursitis is common with males and females affected equally.
