You need to be evaluated and treated by a Lyme-literate doctor (LLMD). Non LLMDs have no clue about this horrible disease or its complex treatment!
A LLMD is one who has treated Lyme disease and the co-infections which come with it for many years and has gotten patients well. A good one will follow Dr. B's Guidelines, the "gold standard" for Lyme treatment.
Unfortunately, LLMDs are far and few between so you need to go where they are. At least half of all Lyme patients travel out-of-state for their care.
Also, most LLMDs do not accept insurance due to the politics surrounding this horrible disease. Read poster TF's explanation, "Why Lyme Doctors Don't Take Insurance":
Read the books written by the top LLMD, Dr. H titled, "Why Can't I Get Better?" and his new one, "How Can I Get Better?". It is an excellent source of information.
Also read "Cure Unknown" by Pamela Weintraub. Check your local library or buy it used on Amazon.
