The main symptoms of stenosing tenosynovitis are soreness and pain in the fingers and a tendency to form nodules in the location of the tenosynovitis, which can be painful after pressure.
Also, if the stenosing tenosynovitis is severe, there may be morning stiffness of the finger in the morning, or the finger may be unable to move in a certain position and needs to be broken or straightened before it can be moved properly, which is called snapping finger as well as trigger finger.
The main cause is the inability to move the finger due to the tendon becoming trapped in the tendon sheath, and the popping of the finger during movement is also caused by the tendon sheath becoming trapped.
