You know, I actually stumbled across this thread from google while searching for "sore fingertips" and not even relating it to diving. When I saw scubaboard show up in the search results, I just remembered that I did two dives yesterday. Must be the cause of my problem!!!
I don't really think it's any form of DCS. I was doing kelp maintenance with SMBK yesterday, which is in super shallow waters (no more than 30 feet). I would probably blame this condition on a mix of cold hands and manipulating a wetsuit. I wear 1.5mm gloves in SoCal (very cold, but I enjoy the dexterity). So my hands get nice and frozen every dive. Pulling on a wetsuit with cold hands probably does some kind of minor tissue damage or something. I'm no doctor, but this is what I think.
