Tennis elbow, medically known as lateral epicondylitis, is a painful condition affecting the tendons that attach to the outer part of your elbow. Despite its name, this condition affects more than just tennis players – it commonly develops in people who perform repetitive arm and wrist movements. The condition involves inflammation and micro-tears in the tendons that control wrist extension, particularly where they attach to the lateral epicondyle (the bony prominence on the outer elbow).
- Mild discomfort on the outer elbow after activity
- Slight tenderness when pressing the lateral epicondyle
- Minor weakness in grip strength
- Occasional pain with wrist extension
- Stiffness in the elbow after periods of rest
