Trigger Finger

The tendon that bends the finger passes through a tube-like tendon sheath. Repetitive gripping action can cause the tendon and sheath to become irritated, inflamed or enlarged. This makes it difficult for the tendon to pass through easily. Further, trigger finger is another name for the condition because the tendon catches and then suddenly releases, as if clicking a “trigger.”

You can treat discomfort and swelling with rest, activity modification, anti-inflammatory medication, or steroid injections. If the tendon does not return to normal, a minor surgery may be necessary.
