I have some type of parasite on my arm, other place and in my eye, doctor said fungus but it's not. Creams didn't work, anti parasite all natural didn't work. Had mri's cat scans blood test even a colonoscopy. Nada. Doc looked at me like I wasted time and resourses, said I was a hypercondreact, not sure if I spelled that right. Anyways, I ordered praziquantel off ebay, cheapest place I could find. Well I had a Tapeworm that is nearly gone. Then I went to tractor supply aND picked up apple flavored dewormer for horse. Sores on arms disappeared. Eyes got better. I weigh aprox 170 and I ingested 250 lbs worth, it's a dial on the wormer. Well after a couple weeks they came back. I would recommend to check and read thoroughly on dosages for humans and do regular treatment till you get rid of the problem.
