Bursitis is the inflammation or irritation of the bursa – which is a sac that is filled with a lubricating fluid that is located between tissues such as bones, muscles, and tendons to decrease the friction and irritation associated with movement. Bursitis is most often caused by repetitive movements and age. Overuse of a joint can increase a person’s risk of bursitis. Such activities include tennis, golf, throwing, and gardening. Age also affects who will develop bursitis. As tendons age they are less able to tolerate stress, and they become less elastic, making them easier to tear and deteriorate.
