What mimics tennis elbow pain?

Lateral epicondylitis (epicondylalgia) involves the common extensor tendon attachment to the lateral epicondyle of the humerus, namely the extensor carpi radialis brevis (ECRB). However, other causes of lateral elbow pain can mimic tennis elbow, including brachioradialis trigger points, extensor carpi radialis longus (ECRL) trigger points or tendinitis, and radial tunnel syndrome.

What’s tricky about lateral elbow pain is that all three areas may be tender to palpation. If that’s the case, the client’s history and other physical exam findings are needed to reveal the primary source of pain.
