What causes tennis elbow and golfer's elbow?

Tennis elbow is a common injury that involves the outer part of the elbow. But most people that get it don't play tennis or any other racquet sport. It's often caused by doing the same type of activity over and over (overuse). This might be manual labor or playing a racquet sport. Tennis elbow might also be caused by simply doing daily activities at home, like chores.

Tennis elbow is usually a long-term (chronic) overuse injury. At first, when someone develops more sudden (acute) tennis elbow, there is some inflammation within days or weeks. As the body tries to heal itself, the tendon can become thick. That can cause pain known as “tendonitis” or “tendinopathy.” As time goes on, the tendon becomes thick and wears away (degenerates). Note: tennis elbow does not always involving  inflammation of the tendon, or tendonitis.

The muscles that move your wrist and fingers are attatched at your elbow.  Repetitive movements of these joints can cause overuse injuries such as tendonitis.  Tennis and golf are just some of the motions that can be associated with this tendonitis.

Nothing in the body works in isolation. This holds true for tennis and golfer's elbow. Often elbow pain is a response to a series of problems beginning with the shoulder blade. When the shoulder blade is not functioning well the arm bone (humerus) then rests and moves abnormally. The forearm then responds to these impairments by adapting to limited or excessive rotation of the forearm. Although the pain for these issues is thought to derive from the forearm extensor or flexor muscles, they are actually responding to deeper movement impairments involving the interplay between the shoulder blade, humerus, and forearm.

Tennis or golfer's elbow is inflammation or soreness over the elbow, specifically on the lateral or outside area. It is caused by repetitive motions that stress the muscles and tendons that attach to the bone in this area. Tennis players and golfers are prone to this injury because they consistently repeat the same motions in their arms and wrists, but it can occur in anyone who uses their arms in a repetitive manner.
