A tennis elbow, also known as lateral epicondylitis, is an overuse injury that results in pain for the tendons connecting the wrist and fingers and the lateral epicondyle, a bony protrusion on the elbow.
Repeated actions in tennis and similar sports can lead to a tennis elbow. But the condition can be felt by anyone who is engaged in repeated upper arm movements related to recreation, work or everyday activities.
Repeated extending and flexing of the extensor carpi radialis brevis tendon with impact force, like in hitting a tennis ball, can give rise to microscopic tears where the tendon meets the lateral epicondyle.
The tears can give rise to pain, tenderness, and stiffness when bending or straightening the elbow.
A doctor’s physical examination and a check on possible factors related to occupation or sports. An X-ray or MRI may be involved to rule out other possible factors.
