A condition characterized by pain and tenderness on the outside of the elbow and in the back of the forearm. Its medical name is lateral epicondylitis.
Tennis elbow is caused by inflammation of the tendon that attaches the extensor muscles (in this case the muscles that straighten the fingers and wrist) to the humerus. The condition results from overuse of these muscles, causing constant tugging of the tendon at its point of attachment to the humerus.
Tennis elbow may be caused by playing tennis or other raquet sports with a faulty grip, but more commonly due to other activities such as gardening, manual labour (screwdriving).
- corticosteroid injection
- surgery to release the tendon
If it keeps recurring it's wise to take a break for a couple of weeks from raquet sports to see if that's definately what's causing it and then if it is seek professional advice is playing technique and equipment.
