my skin "itchies" were a precursor to my uc - had em on my legs for almost a year before my colon puked on me -
itchies finally went away when i quit eating grains - oh, and what a coinkadink (as my wife and i'm sure a few others say), my uc took a vaca ! go figger
chicken or the itchies ? which came first ? dunno - but probably your wacked out pooper hole is not liking something your putting in there !
