What is a major symptom of epicyndylitis?

A major symptom of epicondylitis is pain at the outside of the elbow. This condition, often referred to as "tennis elbow" when it affects the lateral side, results from inflammation or microtears in the tendons of the forearm muscles that attach to the bony prominence of the elbow. Patients typically experience pain and tenderness specifically on the outer part of the elbow, which may worsen with activities that require gripping or lifting.

In contrast, complete joint immobility is not characteristic of epicondylitis; while pain may limit movement, the joint is not completely immobile. Intense abdominal pain is unrelated to epicondylitis, as this condition is focused solely around the elbow region. Lastly, bone fractures are distinct injuries that would present different symptoms and are not indicative of epicondylitis. Thus, pain at the outside of the elbow accurately describes the primary symptom associated with this condition.
