DEAR DOCTOR K: I have a painful trigger finger on my left hand. What caused it, and what can I do about it?
DEAR READER: The term "trigger finger" may conjure up visions of sharpshooters and hunters -- people who sometimes are too quick to draw their guns. To doctors, however, "trigger finger" refers to a condition that occurs when the finger briefly locks and then suddenly releases as you try to bend or straighten it. This often causes a snapping sound.
