Bursitis may be caused by:
- A blow to an area containing a bursa
- Repetitive stress on the bursa
- Infection in bursa
- Long periods of pressure on joint—leaning on elbows, sitting or kneeling on hard surfaces
- Medical conditions that cause inflammation in joints such as rheumatoid arthritis or gout
If the stress is not relieved, bursitis can become a long-term condition.
