Tennis elbow is a condition in which the tendon that attaches the elbow joint to the forearm muscle becomes inflamed due to overuse or degenerative changes. The main symptoms of tennis elbow include pain and soreness on the outside of the elbow and weak grip strength.
Sometimes, tennis elbow is caused by weakening of the forearm muscle due to overuse. In other cases, the cause of tennis elbow is unknown. It occurs most frequently in those ages 30 to 50. Treatment for tennis elbow includes physical therapy, arm braces, NSAIDs to reduce pain, and surgery only in rare cases.
