The success of rehabilitation of tennis elbow is dependent upon first controlling the inflammation at the insertion of the extensor tendons into the Humerus bone, on the outside of the elbow joint (see full article for an explanation of the anatomy).
Depending on the severity of the condition, this may be alleviated simply by rest or with the use of anti-inflammatory medication or a corticosteroid injection. In some longstanding cases, where there is degeneration of the extensor tendons, anti-inflammatory medication, especially corticosteroid injections, should be avoided. This is because they can hinder tissue healing and in fact cause more degeneration.
In severe cases, where a corticosteroid injection has been given, some doctors
insist on a 10 day rest period before rehab is initiated. Unless this is adhered
to the following exercises are likely to aggravate the problem. If the progression
is timed correctly, all of the exercises should be pain free.
