Pupps is awful! I have a mild case of it right now. I had it with my previous pregnancy as well. Get yourself some Grandpa's pine tar soap STAT, it really stinks but feels fantastic. Also, I take Sam-e, and it is supposed to help the liver detox. That's what has worked for me. Oh, and try as hard as you can not to itch it like crazy (if it is pupps) because it spreads quickly.
Hope it is just the regular old pregnancy itches though
