tendonitis is usually caused by overuse of a muscle group or joint. repeated sliding of the tendon during heavy use especially when a person is unaccustomed to it can result in irritation causing pain in and around the tendon. “tennis elbow ” or lateral epicondylitis is an example of tendonitis resulting from overuse or strain. other sports activities (e. g. golf) and chores (house painting) can cause tendonitis too. for some people with tendonitis no repetitive activity can be blamed as a cause; wear-and-tear from aging probably plays a role in these cases of tendonitis. using proper swing mechanics in tennis and golf and trying not to overdo it when starting a new activity are the best ways to avoid tendonitis. should i get an xray to determine whether i have a tendinitis or fracture round my knee?
