De Quervain’s tenosynovitis is tendonitis that is caused by overuse of the wrist next to the thumb. The overuse causes inflammation of the tendons between the thumb and the wrist. When the tendons move through the tunnels, the inflammation can cause numbness and tingling.
Common symptoms of de Quervain’s tenosynovitis include:
- Tenderness of the thumb & wrist
- Pain in the thumb & wrist
- Weakness in the thumb & wrist
Patients with symptoms of de Quervain’s tenosynovitis complain of pain during normal activities including writing, typing and any simple thumb movement.
Treatment for de Quervain’s tenosynovitis includes wrist splinting and physical therapy. If those treatments do not improve symptoms, then cortisone injections and/or minimally invasive surgery can treat de Quervain’s tenosynovitis.
