What is "bursitis"?

Bursitis is a condition that happens when the small sacs filled with fluid called bursae, which cushion and protect the joints, get swollen. This swelling can lead to pain and stiffness, particularly around the affected joint. Bursitis often affects areas such as the shoulders, elbows, hips, and knees, where repetitive movements or pressure can irritate the bursae. Risk factors for bursitis include overuse or repetitive motion, injury, and certain medical conditions such as arthritis or diabetes. Treatment typically involves rest, ice, compression, and elevation to reduce inflammation and relieve symptoms. In some cases, medications such as pain relievers may be recommended to manage pain and swelling. In severe cases, injections with anti-inflammatory medicine or, rarely, surgical drainage of the bursa may be necessary to relieve symptoms.
