I know I most certainly don't have to convince you JC. You have been through the wringer and still going through it!
For myself, I know I have them crawling out and through my butt and vag and feel them in my saliva glands, throat and nose. I also think they may be in my lungs and have felt very similar feelings in the urinary tract and have had a difficult time getting the pee out a few times. They most likely also caused the anal fistula. I'm having trouble sitting still long enough to type this because of them coming out of the fistula opening. I keep jumping up to try to catch them but they are just too friggin' quick!
And this is just pinworm that I'm researching! What other parasites am I going to find that I have and what awful things they can do to the body.
