Bursitis is inflammation of a bursa. A bursa is a thin sac that lies between bone and soft tissue near certain joints. A healthy bursa allows smooth movement of soft tissue over bone. Inflammation can make it painful to move the nearby joint.
Bursitis occurs most often in the:
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.
Factors that may increase your chance of bursitis include:
- Repetitive motion activities when done to an extreme, such as swimming, running, or tennis
A job that requires:
- Repetitive motions such as hammering or painting
- Long hours in one position such as a carpenter kneeling
- Contact sports
- Sporting gear that is too tight
- A puncture or deep cut that involves bursa
Bursitis may cause:
- Pain in the area
- Reddened skin
- Warmth around the area of the bursa
- Decreased motion of the nearby joint
- Decreased function of the nearby limb
You will be asked about your symptoms and your physical activities. The painful area will be examined.
Images may be taken of your bodily structures. This can be done with x-rays .
Bursitis treatment will focus on decreasing inflammation and pain. The main step is to stop the activity causing the pain. You will be asked to rest the area and protect it from injury. Your doctor may also recommend:
- Applying ice to the area in the first few days
- Nonsteroidal anti-inflammatory drugs (NSAIDs) for inflammation and pain
- Crutches or a cane if knee or hip bursitis needs support
If the bursitis is painful, your doctor may recommend a corticosteroid injection. These injections have short-term benefits and some risk. They may be limited to conditions that interfere with daily activities.
Chronic bursitis may need more aggressive treatment. Additional steps may include:
- Physical therapy—sessions may include exercises and heat therapy
- Surgery—only if all other treatments are not effective
To help reduce your chance of bursitis:
- Do not overdo sports and other activities.
- When doing a new activity, gradually increase the intensity and duration of activity.
- Make sure you perform activities correctly.
- Wear properly fitting, protective pads if you play contact sports.
- Use proper safety equipment at work.
- Work with an ergonomic specialist to improve work related activities.
