De Quervain’s Tenosynovitis is a painful inflammation of the tendons of the wrist on the thumb side. Pain is usually worse with moving your thumb away from your hand, grasping, and moving the wrist side to side. The tendon is often thick and swollen. The most common cause is overuse and repetitive activities. Fun fact: this type of tendonitis is often found in new mothers due to the way we lift our babies! Our therapists are trained in assessing and treating De Quervain’s tenosynovitis and will get you back to doing the activities that you love.
