When a person has 'trigger finger,' it means his or her finger is stuck in a bent position, according to Mayo Clinic. When the finger finally straightens, it usually does so with a snapping noise, similar to a trigger being pulled.
Trigger finger is common in people who use repetitive gripping actions in their jobs or hobbies. It is also more common in women than men and is often seen in those with diabetes. It is a condition that occurs when the space that houses the tendon becomes inflamed, notes Mayo Clinic. Treatment plans vary based on the severity of the condition, and in severe cases, the finger may remain in the bent position.
