I have experienced intermittent episodes of a cold, "wet" feeling on the tip of my right index finger (palm side up). I am right handed if this helps, and I do use my iphone and computer alot. Nothing obvious to cause this (i.e. injuries, medication changes, etc). I have no other symptoms around my fingers, hands, or wrists, but could this be the beginnings of Carpal Tunnel Syndrome or a pinched nerve somewhere? Possible I am simply being hyper-vigilant about my body and nothing more?
