Tennis elbow is a common condition which occurs as a result of repetitive activities. The pathologic process behind it is chronic degeneration of the extensor-supinator origin.

Most cases will clear up with activity modification, stretching and NSAIds
Injections for tennis elbow are indicated when there is chronic pain and disability or functional impairment as a result of the pain.
