Do a Dark Field Microscopy test, i think Fry Labs is doing it in the US.
frylabs.com/investigational-diagnostics/If positive, go to your neuro with the video recording showing your blood as a Disneyland for spirochetes. If after this he will still say "you once had" the infection, then it is time to say thank you and leave his office for good, and find an LLMD....
Immunosuppressants have triggered my latent lyme in the first place, it made all my symyoms many times worse , lost 20 pounds in one month. So be careful... Im not saying never take steroids, but if the DFM shows an infection in your blood you really dont want to take them.
