Thank you! Do you think the lyme test is accurate, then?
Yes. I think the positive Lyme test is accurate.
Just so you understand, Lyme can sometimes cause autoimmunity such as positive RF factor antibodies. It is not uncommon for those autoantibodies to normalize after Lyme and coinfections are adequately treated.
Your symptoms definitely seem to indicate bartonella, as well, which greatly affects the bones, joints, tendons, and feet, as well as many of the other symptoms you mentioned. An LLMD is the type of doctor you will need.
Steroids will only make the Lyme and coinfections worse, as it will suppress your immune system, and will not fix the root of the symptoms, which is infections.
