Elbow Bursitis

Elbow bursitis is the condition that causes fluid to collect in a sac (the olecranon bursa) that lies behind the elbow. A bursa is a slippery, sac-like tissue that is designed to allow smooth movement around bony prominences, such as the point behind the elbow. If a bursa becomes inflamed, the sac then fills with fluid. This can cause a noticeable swelling as well as considerable pain behind the elbow.
