De Quervain’s Tenosynovitis
De Quervain’s Tenosynovitis involves your thumb and the tendons on that go over the wrist to your thumb. The cause of De Quervain’s Tenosynovitis may be overuse when lifting or performing side to side motions with your hands. Working in the garden, playing golf or picking up a baby are common activities that can lead to De Quervain’s Tenosynovitis.
Common symptoms may include:
Pain and/or swelling near the base of your thumb and along the thumb-side of your wrist.
Pain that radiates from your thumb that then runs along the thumb side of the forearm especially when bending your wrist down as you make a fist (Finkelstein's Test).
It's difficult to make a fist, grab an item or cradle the back of an infant's head with your thumb outstretched.
You have tenderness with pressure over the tendons at the bottom of your thumb.
