OUCH! Your finger pops and then locks in a bent position. This is called trigger finger, and it happens when the tendon in your finger develops an abnormal nodule and is caught in the opening of a tunnel through which the tendon naturally passes.
Trigger finger can be caused by diabetes, arthritis, gout, repetitive motion, or a hand or finger trauma.
Steroid injections usually help, but an operation can release the tunnel that traps the tendon. Dr. Harris can perform the surgery at his facility under local anesthesia, and most people are back to work in a week or two.
