Trigger finger is a condition in which one of your fingers gets stuck in a bent position. It can be very painful. The finger may straighten with a snap or pop, like a trigger being pulled and released, hence the name. There may also be a bump over the joint in the palm of your hand. In severe cases, your finger can become locked in a bent position. Trigger finger happens when tendons in the finger or thumb become inflamed. This is usually caused by repetitive gripping movements and people whose work or hobbies involve this are more at risk e.g. farmers, industrial workers or even musicians. Trigger finger more commonly affects your thumb or your middle or ring finger and is more pronounced in the morning. It is seen more often in women than in men. The condition is diagnosed with a physical examination of the hand and is treated primarily with rest. Your doctor may put a splint on the hand to keep the joint from moving and may recommend gentle exercises to help maintain mobility in the finger.
