I am just catching up with your posts and I may have joined a little late. What doctor did you see, how did you find him? It sounds like youve been a quite a lot and I have myself but I don't know your story so if you can link me to your story (if you wrote it out here?) it would be awesome.
Did you ever try Metametrix stool test? They use DNA PCR for testing for E. Histolytica which should show up no? Wouldn't it at least show up on a really sensitive DNA stool test even if the parasite is found in the tissue due to excrements?
What kind of symptoms did you have? I've been house bound and unable to leave my room for 3 years now, age 24. IT SUCKS MAJOR crap. Would help if you could answer those questions! And if you know of any doctor in California.
