I did get 2 positive stool tests, so that is how I found out about the Ascaris and protozoa. An MD identified the hookworms. The skin issues I had to research myself. I started with a few rounds of albenza and ivermectin prescribed by doctors, but not enough to stop anything. I then went to Dr. Yu in St. Louis and got heavy dosing. Mostly, the protocols can be found here on CZ by various people who have worked thru their parasite problems and are kind enough to post here what works for them. ICU has posted some protocols here that many seem to have found effective. In my case, I found the little black worm things went away with the albenza and ivermectin, plus I soaked in Epsom Salt baths with either Mule Team Borax or cider vinegar added, sometimes I added hydrogen peroxide. Then I would air dry in front of a heater.
