What is tennis elbow?
Tennis elbow, also known as lateral epicondylitis, is an injury caused by repetitive strain to the tendons and muscles around the elbow joint. It is usually caused by activities that require repetitive gripping, twisting or wrist flexion and extension. Symptoms of tennis elbow include pain and tenderness in the elbow, a weak grip and difficulty extending the arm. Treatment typically involves rest, pain relief, and exercises to strengthen the muscles around the elbow.
