I get these little like "blisters", about the size of the head of a straight pin, if not smaller, on my hands, usually my fingers. I got the last year, and they seemed to have come back. I might have been getting them for years, but was drumming from 05 - 08 and might have passed them off as blisters from drumming. I'm trying to figure out what these little "blisters" are and if they are anything serious. Ooh and they like to cluster.
