What should you know about tennis thumb pain?

Racket grip, forceful serves and repeated thumb movement can irritate tendons or strain the small joints and supporting tissues. Pain at the wrist-side base of the thumb, especially with gripping or lifting, can be a presentation of De Quervain's tenosynovitis, but that symptom does not establish the diagnosis. Pain after a specific impact raises different concerns, including a sprain or fracture. Swelling, clicking, reduced motion and tenderness help a clinician narrow the possibilities.

Pause painful strokes and avoid forceful pinching until the thumb settles. Keep gentle, comfortable movement rather than holding it rigid for long periods. A cold pack wrapped in cloth may help after activity. Review grip size, technique and recent training changes. A clinician or physiotherapist can advise on support, targeted exercises and whether the thumb or wrist needs examination or imaging.

Get assessed if pain continues, grip is weakening, or everyday tasks such as opening jars become difficult. Seek prompt care after a fall or direct blow, or when the thumb looks crooked, becomes markedly swollen, loses sensation, or cannot move normally.

Ask which structure is painful, whether a thumb or wrist support would help, and which movements should be limited. Ask when strengthening and racket practice can restart safely.
