Bursitis is a painful condition that affects the joints. Bursae are fluid-filled sacs that act as a cushion between bones, tendons, joints, and muscles. When these sacs become inflamed it is called bursitis.
Some causes of bursitis include:
Tennis elbow: Bursitis is a common problem among tennis players and golfers. Repetitive bending of the elbow can lead to injury and inflammation.
Clergyman's knee: Repeated kneeling can cause injury and swelling to the bursae in the knee area.
Shoulder: Repeated overhead lifting or reaching upwards can cause bursitis in the shoulder.
Ankle: Injury to the ankle can result from walking too much and with the wrong shoes. It is common among ice skaters and athletes.
Buttocks: The bursae in this area can become inflamed after sitting on a hard surface for a long time, such as on a bicycle.
Hips: Some runners and sprinters can develop hip bursitis.
Thigh: Bursitis can be caused by stretching.
