Yes, I have blood tests on my liver done every six months. Thanks for responding. I am quite sure it is the Lipitor for things are slowing beginning to clear up. I tell you one thing I feel sorry for people that have allergies like this on a daily basis and can't find out what is wrong. They simply drive me nuts. I am sleeping, and this morning I am not itching as much. I was told the medication was not for itching, but to get rid of the rash. Again, thanks for responding. - sam
