Trigger finger is a condition in which one of your fingers gets stuck in a bent position. Your finger may bend or straighten with a snap — like a trigger being pulled and released. Trigger finger is also known as stenosing tenosynovitis. It occurs when inflammation narrows the space within the sheath that surrounds the tendon in the affected finger. If trigger finger is severe, your finger may become locked in a bent position.
SYMPTOMS:
- Finger stiffness, particularly in the morning
- A popping or clicking sensation as you move your finger
- Tenderness or a bump (nodule) in the palm at the base of the affected finger
- Finger catching or locking in a bent position, which suddenly pops straight
- Finger locked in a bent position, which you are unable to straighte
People whose work or hobbies require repetitive gripping actions are at higher risk of developing trigger finger. The condition is also more common in women and in anyone with diabetes. Treatment of trigger finger varies depending on the severity.
