Trigger Finger | Parkview Health

Pain Conditions We Treat

A trigger finger is a finger stuck in a bent position. It happens when the tendon that bends and straightens the thumb or finger can't slide smoothly under the ligaments that hold the tendon against the bones. In most cases, it's caused by a bump (nodule) that forms on the tendon. The bent finger usually straightens out on its own.

A trigger finger can be painful. But it normally isn't a serious problem.

Trigger fingers seem to occur more in some groups of people. These groups include:

People who have diabetes or arthritis.
People who have injured their hands in the past.
Musicians.
People who grip tools often.

Rest and exercises may help your finger relax so that it can bend.

You may get a corticosteroid shot. This can reduce swelling and pain. Your doctor may put a splint on your finger. It will give your finger some rest. You may need surgery if the finger keeps locking in a bent position.
