The tendon that bends the finger passes through a tube-like tendon sheath. If the tendon and sheath become irritated and enlarged from repetitive gripping action, inflammation may occur making it difficult for the tendon to pass through the sheath. The condition is called trigger finger because the tendon catches and then suddenly releases, as if clicking a "trigger."

Discomfort and swelling can be treated with rest, activity modification, anti-inflammatory medication, or steroid injections. If the tendon does not return to its normal, pain-free condition, a minor surgery may be necessary.
