What are typical symptoms of Lateral epicondylitis?

• A. Pain with elbow flexion at 90°.
• B. Sharp, radiating pain down the outside of the elbow during wrist extension and gripping.
• C. Numbness in thumb.
• D. Pain on inner elbow during supination.

Answer: (B)

Pain over the outer elbow that is triggered by extending the wrist and gripping objects is classic for lateral epicondylitis. This condition is a tendinopathy at the origin of the wrist extensors, especially the extensor carpi radialis brevis, so activities that extend the wrist or require a strong grip place strain on that tendon and provoke sharp pain along the outer elbow.

Other options don’t fit as well: pain with elbow flexion at 90° points more toward issues with the elbow flexors or the nearby neurovascular structures; numbness in the thumb suggests a median nerve issue rather than a tendinous elbow problem; and pain on the inner elbow during supination points to medial elbow pathology, such as medial epicondylitis.
