I don't think I had pinworms, mine started as intestinal worms (and i mean several inches long!) and then things started moving around..i don't itch, i feel like i'm being bitten on the inside and then I see a small pimple like thing appear but with no "whitehead." Tea tree oil is a big relief for anywhere on the skin that is affected but I also feel them moving in my legs, etc and it actually hurts and leaves bruises at times. I so can't wait to see this doctor tomorrow. As for hydrogen peroxide, i gargle with 3%…be very careful with 35%, you can burn yourself severely! I swab my nose, i do an ear wash (10 mins in each ear while laying down) and anywhere i see a bite. I don't drink it intentionally but when i gargle i'm sure some goes in. Enemas would likely give you relief! And DE would more than likely kill them. I like that it's not toxic and actually beneficial for so many things. And they do not build up a tolerance to it because it cuts them up so they dehydrate.
