My fingertips are usually sore after I dive. If I squeeze my thumb and middle finger together it feels sore. It's not a big issue but I'm curious as to why. I used to think this was because of cold water but on the way home from a trip yesterday I noticed it again and the water temps from yesterday's dive were very warm. Is this just sensitivity to the water or something? My fingers feel fine today. COuld it be poor circulation? Anyone experience anything similar?
