Sorry to hear about you symptoms! I'ts very common for Lyme symptoms to come and go. Mine always do. Your symptoms do sound familiar.
there is a test for Lyme from IGenX lab in Palo Alto, Ca that is really good. But first you should try to find a Lyme literate MD. Lyme disease is a clinical (symptom based) diagnosis. The blood work can be negative but you still might have it. That's why you can't rely on tests.
You can find lists for LLMD's online.
Good luck and God bless,
