The stool test is useless its hard to verify the eggs or even the worms in the stool tests.I've just been battling the pinworms for a few months I'm 21 and don't even have any children. I understand your fustration right now I'm trying to eat high acidic foods and cut down Sugar since its what they like to eat off of thr Sugar and the high acid foods to helo kill them off while in the gut and also I've been eating foods that help me poo, like spinach and kiwi and yogurt. Drinking herbal detox tea and I'm trying to take garlic capsules and place it around the infected areas I as well take toilet paper and plug my bum hole so I don't have to feel them nor soread anything this whole time I never experienced itching only was feeling them move around and getting irritation from it but no itching really, I hope for you and myself that we find a cure or something. Now I'm having a hard time cause one of the worms has traveled into my clitoris . I can feel it moving around from there now, so annoying. Good luck to you on your cure and pinworm free journey as well.
