When I had puritis from my sd cycle I tried everything for it. Aveno baths once, it made it worse actually. The only thing that worked for me was ice cold showers. I used to take a shower at the hospital everyday turned all the way to cold full blast!. It was great. I would get a bucket full of ICE and put my bare feet in it, lay down on the hospital bed and go to sleep like that. Hey, they wouldn't give me any drugs, I had to improvise!. Not that this has much to do with the subject of this thread..Sorry Chad. I hope your son is all better.
