It will be good to know what that pain is, i reckon its gallbladder or its an irration of the small intestines like you say, sometimes i edge between them both lol.
Good luck then with the h.plyori as its nowhere easy to beat natalia, my uncle tried naturally for a lifetime then had to go pharm. Its much harder than routine infections, infact even with pharms its a nightmare.
What are your course of plans to beat the h.plyori?
Im having stool tests done too on the off chance, but like i say even once i know im back to the drawing board of do i sit and piss about with anti-parasiticals or do i go full out anti-helmtics to beat this. Many over at the parasite forums are having huge success people.
