Overview

Trigger finger occurs when the tendon that bends a finger becomes inflamed or thickened, making it difficult to glide smoothly through its sheath. This leads to stiffness, pain, and a catching or locking sensation. It commonly affects the thumb, middle, or ring finger and is more frequent in people who perform repetitive hand activities.
