James, please ask your Dr for a copy of your lab reports. Then you can tell us what the western blot says, plus you will have your results for all the other tests on hand. I liked my PCP a lot, but learned right off the bat that he did'nt even look at all the test results (he was the one that ordered them!), also he had not noticed that the lab neglected to do a test that he requested. You may find something helpful in your labs that the Dr doesn't note. Who knows. AT LEAST let's look at your WB. CDC neg means nothing.
We are not Drs, but maybe you/we will note bands in the test that raise suspicion or even point directly to Lyme.
