Tennis Elbow (Lateral Epicondylitis)
Tennis elbow is a painful condition caused by overuse of the tendons in the forearm, often due to repetitive wrist and arm motions. It results in pain and tenderness on the outside of the elbow joint.
Overview
Tennis elbow is a painful condition caused by overuse of the tendons in the forearm, often due to repetitive wrist and arm motions. It results in pain and tenderness on the outside of the elbow joint.
Understand this condition
The tendons that connect your forearm muscles to the bone become damaged and irritated from overuse. Specifically, the tendon that helps you lift your wrist develops tiny tears near its attachment point on the outer elbow. Because tendons have a limited blood supply, these micro-tears can be slow to heal and cause chronic soreness.
Why it happens
It happens when repetitive motions overload the tissues, leading to a cycle of injury and failed repair called tendinosis. Triggers include any activity that involves frequent twisting or gripping with the wrist extended. Over time, the tendon structure weakens, making everyday movements painful and reducing your overall grip strength.
Real-world scenarios

- •People may notice difficulty turning a key or opening a heavy door.
- •This often appears as a dull soreness after a long day of typing.

- •Referred pain from tight forearm muscles or trigger points
- •Minor bruising from a direct bump to the outer elbow
- Radial tunnel syndrome causing nerve compression in the forearm
- Septic arthritis, a serious infection within the elbow joint
- Avulsion fracture where the tendon pulls a piece of bone away
- Cervical radiculopathy, where a pinched neck nerve causes arm pain
