What is Trigger Finger?

Trigger finger (‘Stenosing Tenosynovitis’) presents as pain or clicking in the palm on bending of the fingers due to catching and/or irritation of tendons in the palm. Swelling can develop in the tendon creating a nodule which causes more irritation and further swelling. Ultimately, the swelling may get stuck in the tunnel that the tendon passes through, causing locking of the finger.
