Trigger finger, also known as stenosing tenosynovitis, is a condition in which one of your fingers gets stuck in a bent position.
Trigger finger is a condition that affects the tendons in your fingers or thumb. When you try to straighten your finger, it will lock or catch before popping out straight.
Symptoms, like a tender lump in your palm, swelling, catching or popping of your joints, or pain when bending or straightening, may occur randomly, or after a period of heavy hand activity. Symptoms tend to be worse after periods of inactivity. In severe cases, the tendon may break free, feeling much like a joint dislocation.
Treatment of trigger finger includes rest, over-the-counter medications, steroid injections, and in some cases, surgery.
