Overview
Bursitis is inflammation of a bursa, one of the small fluid-filled cushions that reduce friction around joints such as the shoulder, elbow, hip and knee. It usually follows repetitive movement, prolonged pressure or a minor injury, causing pain, swelling and tenderness that worsen with use of the joint. Most bursitis settles with rest, ice and avoiding the aggravating activity; sometimes fluid needs draining or an injection, and an infected bursa needs prompt treatment.
Symptoms
- Pain and tenderness around a joint
- Swelling over the affected area
- Pain that worsens with movement or pressure
- Stiffness of the nearby joint
- Warmth and redness if the bursa is inflamed or infected
When to see a doctor
See a doctor if joint pain and swelling do not settle with rest, or urgently if the area is hot, very red and you have a fever.
Causes
Repetitive movement or prolonged pressure on a joint, minor injury, kneeling or leaning for long periods, and sometimes infection or gout.
