What is Trigger Finger?

Trigger finger is the common term for the condition “stenosing flexor tenosynovitis.” People who have trigger finger will report that their finger is catching, locking, sticking or snapping in a bent (flexed) position.  Sometimes, people cannot straighten the finger without pushing on it.  Pain can develop in the finger and sometimes in the palm of the hand, and there may be a nodule (bump) present over the finger or palm.
