So are you saying that the "crawly feeling" could be hemorroids, rather than parasites?
I have the same occasional crawly feeling around my anus, in my ears, and my nose, and face in general, and occasionally in other parts of body. It drives me insane because I keep imagining parasites crawling all inside my body. I won't touch my husband or my pets because they have not been "wormed". I hate being so paranoid like this, and wish I had never LOOKED at any photos of parasites! I feel like I will never be a "wife" again, as I refuse to even kiss my husband until we finish our cleanse!
One of my poor dogs came up to me and licked my leg when I came in the door from work last night-I totally freaked, scrubbing my leg! I need to get over this paranoia of parasites, but I don't know how! Waiting on my HumaWorm parasite cleanse to come in the mail, and eating pumpkin seeds and garlic nonstop! LOL
