Overview
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.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
How can you care for yourself at home?
- If your doctor put a splint on your finger, wear it as directed. Don't take it off until your doctor says you can.
- You may need to change your activities to avoid movements that irritate the finger.
- Take your medicines exactly as prescribed. Call your doctor if you think you are having a problem with your medicine.
- Ask your doctor if you can take an over-the-counter pain medicine, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve). Be safe with medicines. Read and follow all instructions on the label.
- If your doctor recommends exercises, do them as directed.
