What is Bursitis?
Bursitis is a condition of inflammation or irritation in the bursa. The purpose of the bursa is to decrease rubbing, friction and irritation between tissues such as bone, muscle, tendons and skin.
General Causes of Bursitis
Most often the cause of inflammation in the bursa is overuse of the joint. Overuse injuries can create inflammation or irritation in the bursa. Bursitis is generally seen in patients over 40 years of age. As tendons age they are able to tolerate less stress, are less elastic and are easier to tear. There are three joint locations that contain bursae that may be affected by inflammation of the bursae: the shoulder, the elbow, the hip and the knee.
