Trigger Finger

Trigger finger is a condition that makes your fingers or thumb difficult to move. It can “freeze” them in a flexed position. It affects the tendons in your fingers and thumbs. Trigger finger gets its name from the position your fingers can get stuck in — it looks like you’re trying to pull an invisible trigger.

If you have trigger finger, your affected fingers or thumb can be stuck flexed in toward your palm. It can be hard — or impossible — to straighten your affected digits (the medical term for your fingers and thumb). Trigger finger can affect any of your digits, but people most commonly develop it in their ring fingers (your third finger).
