Causes could include:
|
Trigger finger is the popular name of stenosing tenosynovitis, a painful condition in which a finger or thumb locks when it is bent (flexed) or straightened (extended).
|
|
Your doctor can tell if your flexor tendon is cut by examining your finger. If the wound is very deep, the finger may be x-rayed to make sure the bone isn’t damaged, too.

Tendonitis is your body's way of telling you, "Enough! You're putting too much stress on this muscle and joint."
