Your symptoms sound very much like those I had 20 years ago. I suspected parasitic infection and even went to Mayo Clinic when no local doctors would listen to me. Mayo was no help either - I treated symptoms and things went dormant for about 17 years, then everything reemerged big time. I have now been treating with a lot of anti-helminths for 3 years. I follow a protocol called Sharkman's Protocol. Hopefully you can find it here by searching. Just want to say, do your research and treat it now even though your doctors aren't helping you and hopefully you can nip it in the bud. If going to Asia for treatment is a possibility for you, that sounds like a great choice. I have read accounts here on CZ of some patients who have gone to Asia for treatment.
