Did you have parasites in those areas before you started the drugs? If not then they probably scattered. I had that happen to me once. I stopped all drugs and let them settle back down in my GI tract. Then I used different things to try to kill them. Consider looking in the book, "Healing the Gerson Way". She builds the body with juicing and gives directions for coffee enemas, etc. Ya gotta be strategic with these things and change things up no matter what you use. When one thing doesn't work, don't quit. Keep hitting them from a different angle.
