It seems that there are a number of us that have all the signs of pin worms but are unable to see living worms. Were you involved when my pin worm saga got thrown into the debate forum?
I have seen dead worms when I used the zapper (which just help to scatter them) and saw some on stool but only before I started using psyllium and DE when my turds were hard. Then when I got desperate for some relief and stuffed a zinc tab up my butt (it hurt like hell after a few times). There were hundreds of tiny white worms after the first time but I have yet to see one single living worm.
As others have posted, there is only one thing that feels like a pin crawling out your butt, as far as I know. It's a very distinct sensation that cannot be easily confused with anything else.
I've seen a lot of posts where people say they are easy to see but that has not been the case for me. I wonder if it's possible that they have mutated and are not the same old reliable pin worms that they used to be.
If it feels like a pin worm (as it crawls out yer butt and other privates) and it itches like a pin worm, it probably IS a pin worm.
No one yet has been able to tell me what else mine might be. All the months researching these things and I still can't come up with one other parasite that crawls out your butt and then back in. If anyone knows of something else, please tell me!
As you well know, things have changed and perhaps the pins have too. I dunno!
