Sounds like rushing and not listening doctors. There is more of that these days. On the Lyme issue (still not trying to prove you have it) - there are only about two labs in the country (mainland) who truly can test for the more subtle indicators of Lyme, most doctors send blood to just any old labs. The Western Blot test has several indictors and a certain amount of them is needed to make the diagnosis, but the special labs I make reference to use a more proprietary testing method and then the doctors also need to be a little less stringent in markers. The CDC gives certain specifics on their web site but add that they are only research suggested guidelines - not the be all/end all for diagnosis. Dry mouth and dry eyes raises potential for sjogren's syndrome - but I'm not and MD. See if you can find a more user friendly doc. It is scary to have medical issues and not enough answers.
