Re: Can someone tell me how pinworms really look?

No you're not, I know what you mean. Sugar makes every critter party all night, worms, candida, bacteria, I'm guessing viruses too, except for protein-loving ones. Anyway, drugs can be ineffective and parasites can be resistant to them. Have you tried the natural dewormers? (Black walnut, Wormwood , cloves, garlic etc)Lots of good info here.
I'm working on doing some parasite cleansing, colon cleansing, and then liver cleansing. FYI, food allergies and hemmorrhoids can also casue itching there. Not sure about the sensation of movement though...and Sugar would make a difference unless it's really a microbe or critter.
Diatomaceous earth is also used to get rid of worms but I'm not sure how to apply it externally. I hope you will find your remedy and won't have to suffer for several years like me.
