In the very beginning of my first parasite cleanse, I broke out in hives all over my chest, abdomen, and under my forearms. It totally disapeared in about 3 days, leaving no marks or signs of rash.
I had never had a rash before this in my life. I'm sure it was due to your cleansing, you are doing quite a bit all at once. Just my opinion, but yours could be lasting longer due to a higher level of toxins. My opinion is that it is die-off, and stick it out and get it all out.
