Sorry to hear what you are going through. If your doc is not highly experienced in Lyme disease, then I would consider locating a Lyme specialist for a second angle for you and for your son. Sorry that's not much of an explanation, but once you have the test results back, then the path may be clearer. Please let us know how you do -- and don't give up! Lyme can indeed be beaten, with the right doc, the right diagnosis, and the right treatment.
