The main cause of trigger finger is swelling and inflammation around the tendon. Without treatment, the finger may become locked in the bent position. People who have hobbies or jobs that require repetitive gripping or squeezing are more likely to develop trigger finger, as are people with diabetes.

Trigger finger treatment can range from rest to surgery, depending on the severity of your condition. Resting your hands if possible, wearing a splint at night, stretching exercises and a steroid injection all can alleviate trigger finger without surgery.

Diclofenac topical (Zorvolex, Zipsor, Cambia, Cataflam, Voltaren XR) NSAIDs inhibit inflammatory reactions and pain by decreasing prostaglandin synthesis.
