Treatment for de Quervain's tenosynovitis may include medications, physical or occupational therapy, or surgery. Treatment is generally successful if begun early on, though the pain may recur if you can't discontinue the repetitive motions that aggravate your condition. If you start treatment early on, your symptoms of de Quervain's tenosynovitis should generally improve within four to six weeks. When de Quervain's tenosynovitis starts during pregnancy, symptoms usually get better around the end of pregnancy or when breast-feeding stops.
Complications of wrist surgery include infection and healing problems. A small nerve, called the sensory branch of the radial nerve, can be damaged leading to a patch of numbness on the back of the thumb. One of the more concerning complications is that the tendons can become unstable, snapping out of their normal location on the side of the wrist, after the tendon sheath of the wrist is released. This problem can be prevented by ensuring the tendon sheath is opened in the proper location, and by limiting specific wrist movements after surgery.
