Unfortunately, sometimes they are! HUMAWORM explained in the his previous post in this topic:
"The rice "crawlers" could be a variety of parasites OR parasite larvae trying to escape the HUMAWORM. They will try to get out any way they can - they may have been settled in just under the skin - growing bigger so they could then migrate to a different part of your body to fully mature and reproduce. I am not trying to "gross you out" - I just want you to understand what's going on during your cleanse. "
I have come to the conclusion that is what is happening to me. The rice "crawlers" have settled in just under my skin. Thankfully, they are now much better!
