Trigger finger, (aka stenosing tenosynovitis) is a condition in which one of your fingers gets stuck in a bent position. It can be extremely painful throughout the hand, finger and joints.

Your finger may straighten with a snap, like a trigger being pulled and released. Trigger finger 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. 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.

DO YOU HAVE TRIGGER FINGER?

Signs and symptoms of trigger finger may progress from mild to severe and include:

 

  • 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 straighten

Trigger finger more commonly affects your thumb or your middle or ring finger. More than one finger may be affected at a time, and both hands might be involved. Triggering is usually more pronounced in the morning, while firmly grasping an object or when straightening your finger.
