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.
