Please help me. My only positive stool test was in march 2008 for blastosis hominis. Since then they have been negative, but i still have itching and crawling coming from my rectum and they crawl all over my body. They feel like tiny ants or crabs, but they are microscopic and so i can't see them. I have tried several different herbal products, but they just expel them from my rectum and that makes them crawl all over my body that much more. I am getting ready to finally try humaworm formula (should receive any day now after waiting one month for order). I am hoping for some diahreah to help get rid of these creatures. I feel like i am living in a horror movie and can't escape. This has been going on for 9 months. I took alinia, batrim, yodoxin, vermox and flagyl. The bactrim slowed it down. The vermox killed some adults. I am scared to death because i am allergic to antidepressants and this is upseting. My dermatologist says i have delusional paritosis and never even tested or scraped my skin. She said there are no red bumps, so i am fine. I need to find a new dr who specializes in parasites in the houston, texas area. I am desperate. Please help me. signed rejected
