Diagnosis

To diagnose de Quervain's tenosynovitis, your doctor will examine your hand to see if you feel pain when pressure is applied on the thumb side of the wrist.

Your doctor will also perform a Finkelstein test, in which you bend your thumb across the palm of your hand and bend your fingers down over your thumb. Then you bend your wrist toward your little finger. If this causes pain on the thumb side of your wrist, you likely have de Quervain's tenosynovitis.

Imaging tests, such as X-rays, generally aren't needed to diagnose de Quervain's tenosynovitis.
