Bursitis

Overview

Bursitis is inflammation of a bursa one of the small fluid-filled sacs located near joints in the knee elbow shoulder and wrist that act as cushions to reduce friction when your muscles rub against bones or tendons.

Causes

There are various causes for bursitis including traumatic injury such as those resulting from a car accident or a serious fall. Rheumatoid arthritis may also contribute to bursitis. The main cause however is repetitive movement. Excessive use irritates joints and tendons causing them to swell. This often happens in a work environment where someone for example keep their arms extended above shoulder level for long periods of time or those who are constantly putting pressure on their knees.

Symptoms

Pain is the one common feature of bursitis but in some cases particularly when the shoulders are involved there may also be some restriction in movement.

Treatment

In order not to further worsen the condition and to help it heal you must avoid whatever activity has caused your bursitis. Anti-inflammatory drugs and pain relievers may also be prescribed. Occasionally cortisone injections are prescribed. If movement is restricted simple exercises may help to increase your range of motion.

Prevention

Preventing bursitis is a matter of avoiding or limiting the kind of activity that contributes to it or ensuring that you are protected from constant pressure on your joints. If for example you must kneel for long periods of time you should use knee pads. For shoulders raise yourself up closer to your work instead of constantly reaching up. Developing strength and flexibility can also protect the bursa and the joint.
