I'm new to this too, so my answer my not be the best....first off, acne does not itch. So it's probably not acne-it could be just the toxins leaving your body. I'm sure it will eventually go away-after your parasite cleanse, do a liver cleanse about one week later! I've heard that really clears things up! The itchy anus is parasites-pinworms in particular. The best thing would be maybe an enema with salt in it-worms hate salt! Remember putting salt on snails and how they shriveled up and died? Same concept with the parasites! You probably could also mix some salt and hydrogen peroixide on a cloth, and wipe your anus with it, as that's where the pinworms supposedly hang out. I've heard these things really help, but have not tried them myself....good luck!
