Trigger finger

What is Trigger finger?

Trigger finger meaning An irritation of the digital sheath that surrounds the flexor tendons of the finger. When the tendon sheath becomes thickened or swollen, it pinches the tendon and prevents it from gliding smoothly. In some cases, the tendon catches and then suddenly releases as though a trigger were released.
