No I don't think you're crazy!! I too have been fighting pinworms!! For almost 30 years:'( Dr.'s have no clue and done want to hear it... Almost convincing you that you ARE crazy because their little tests come back negative. Recently I have found relief through taking 2-3 tablespoons of Diatomaceous Earth with every meal along with a fiber drink or Colon Cleanse mix to keep me regular... This seems to be key in eliminating the eggs they produce in massive quantities:(
Unfortunately for myself, once I started to get aggressive about changing my diet and taking cleanses, they migrated into my sinuses and eyes!!! I've been all over this site trying to find cures for this new condition. Just read post about ginger and Epsom Salt bath which I'm going to try ASAP.
Anyway, I feel for you. These parasites are no joke and it's so taboo to speak of. I told my husband a couple times as I've gone through different remedies, but because he doesn't have symptoms, has come to the conclusion that I am a compulsive hypochondriac. I now just pretend that it's gone and I'm only keeping up the regimen as a proactive approach. I don't want to gross him out any further. I've not told a soul I know about my new issue with assumed eye worms. It's so discussing and freaky!!!
Anyway... I've also been taking apple cider vinegar which seems to help as well. I've taken some of the meds which I convinced the Dr.'s to prescribe to me, but they only seem to make the worms more aggressive after a day of relief. I think they become immune to pesticides. DE is a physical killer... Look it up. It's cheap and easy. Originally used by farmers for their live stock. I hope this helps.
