I had the same problem, but with my left hand. (maybe it has to do w/whichever hand is dominant?) If you see my post, you can see it got pretty serious. Every time I rode, it got back to the same level. I ended up forced to take a number of days off in a row (unrelated reasons) and my hand finally began to improve. I did also buy new gel gloves, move around as often as possible from the top to the hoods to the drop. I've had a little loss of hand strength since then, but nothing that's incapacitating (sp?). I'll probably switch over to gel tape as well. Hope this helps?
