Numbness has developed in the tip of my left index finger and includes very slight numbness on the top of the finger near the largest knuckle, also.

While often. the numbness of carpal tunnel syndrome is felt in the middle fingers, if only a few nerve fibers are being compressed at the wrist, you might only feel it in your left finger tip. A band of tissue can compress (usually from swelling due to overuse/injury) the nerves that run through the tunnel to the hand.Reduce aggravating activity; try a wrist splint at night for a week or two. No better? To Doc.
