Trigger finger occurs when an irritated tendon prevents you from fully extending the finger, causing it to stay in a bent position.

Here are common symptoms, courtesy of the American Academy of Orthopaedic Surgeons:

  • A tender lump in the palm of your hand.
  • Swelling of the finger.
  • A sensation of popping or catching in a finger joint.
  • Painful bending or straightening of a finger.
  • Stiffness of the finger after a long period of rest.
