When the bursa becomes inflamed, each time the tendon has to move over the bone, pain results. Because patients with hip bursitis move this tendon with each step, symptoms of this condition can be quite painful.
The knee is the largest joint in the body. People use it heavily every day as they walk, run, climb, or jump. As a result, it is also very prone to injury and pain. When these occur, a doctor may recommend exercises to help a person strengthen the muscles around the knee.
Joint pain and swelling become more common as people age. Pain in the knee can make walking, running, and other activities uncomfortable. It can also make it difficult to fall or stay asleep at night.
The lateral collateral ligament, or LCL, is one of the four major ligaments that supports the knee joint. The LCL is located on the outer side of the knee. LCL tears may occur as a result of a twisting type of injury or they may be the result of a direct blow to the inner side of the knee.
