Lateral epicondylitis, commonly called tennis elbow, is an inflammation of the tendons that connect the muscles of the forearm to the elbow. The pain is primarily felt at the lateral epicondyle, the bony bump on the outer side of the elbow.

Symptoms:

• Burning or pain on your outer elbow that may travel to your wrist, often worse at night
• Pain when twisting or bending your arm
• Stiffness or pain when extending your arm
• Swollen elbow joint that’s tender to touch
