Have you done any of the cleanses? Maybe if you start taking the herbs for the parasite cleanse it will clear it up. Also a "detox" vegetable juice diet will help in getting rid of whatever it is that is causing this.
If it looks like a pimple, it is NOT ringworm. My husband had ringworms (a fungus) and they did not look like pimples. They were actually round of the size of a nickel and they form a ring around the skin (with the color of your skin inside of it), and since it's a fungus is under control with the anti-fungal "candida diet."
That's funny how doctors told you it's "folliculitis"-- he just told you that the hair follicles were swollen that's all-- but he did not tell you what caused it. Maybe he doesn't even know.
The Bentonite as recommended above by someone else maybe will work, but I noticed you responded after 3 days or so of taking it that it did not work. The Bentonite has to be taken for a long period of time. It will not work in a few days.
