@brandywine8875 I went to Mayo MN ... My Medicare and Gap insurance paid for it.. My local GP referred me.. Yes, the time and effort was really worth it.. the Local (fairly big Clinic with over 100 doctors) couldn't do diagnose it.. and when they started to prescribe Non-FDA approved drugs I would have to get in Canada or Europe.... that was enough for me.. I had lost 50#... and I was slender and trim to begin with.. I have been to Mayo MN since for Kidney Stones, Urology, GI, Prostate Cancer and Hearing... All were conclusive trips that settled the Issues.. Ken
