What Is Trigger Finger and How Can You Treat It?
Published: Sep 27, 2023
Trigger finger can cause your finger to lock up painfully. Discover what causes it and how you can treat it effectively.
Understanding Trigger Finger
Trigger finger occurs when there's a mismatch between the size of the flexor tendons and the surrounding pulley system in your finger. This mismatch causes the tendon to catch or lock, making finger movement difficult. You might notice snapping or popping sounds, and in severe cases, your finger may get stuck in a bent position.
Who Gets Trigger Finger?
Trigger finger is quite common, affecting about 2% of people, especially women in their 50s or 60s. You're more likely to have it if you have diabetes or rheumatoid arthritis. Although it's rare in kids, if it does happen, it might be due to a genetic condition.
Diagnosing Trigger Finger
Doctors diagnose trigger finger by listening to your symptoms and watching how your finger moves. They may ask you to open and close your hand to see if your finger catches. X-rays aren't usually needed, but they might check for other conditions similar to trigger finger.
