what type of doctor are you going to? A para MD is really an infectious disease doc. I went to a GI doc, and got no where. The only thing he prescribed was mebendozole which really didn't work. That is his only protocal. I then went to a colo-rectal doctor who told me it was "prutitus ani" and I had to get a microscope to prove her wrong. Tried to see an infectious disease doc who wouldn't take me, neither would a gyno. So, I've gotten no where with doctors, and am now on Humaworm. Still not cured, but I think I'm on a better path.
