A bursa is a sac filled with fluid that reduces friction between tendons and bones in major joints like the shoulders, elbows, hips, and knees. The bursa acts as a lubricant so joints can continue to move smoothly. However, these sacs of fluid can become inflamed and infected from overuse and repetitive movements. When the bursa becomes inflamed it is called bursitis.
This type of bursitis affects the bursa located at the tip of the elbow. It is commonly referred to as "tennis elbow" or "golfer's elbow." Olecranon bursitis is usually caused by repetitive motions of the elbow, such as those often used in tennis or golf. Treatment typically involves rest, ice, and heat. In some cases, surgery may be necessary to remove the inflamed bursa.
Bursitis also can affect the shoulder. The bursa is a small, fluid-filled sac that acts as a cushion between the bones and tissues of the body. Bursitis is the inflammation of this sac. When the bursa becomes inflamed, it can cause pain and stiffness in the shoulder. Bursitis often occurs in the shoulder, but it can also affect other joints, such as the elbow, hip, and knee.

Risk factors for bursitis include:
There are several different types of bursitis. The most common type is septic bursitis, which is caused by a bacterial infection. This type of bursitis is usually associated with trauma to the affected area, such as a fall or direct blow. Septic bursitis can also occur following surgery or injection around the joint.
