You need to find a International Lyme and Associated Diseases Society (ILADS) doctor.
I have Lyme and based on my symptoms was able to narrow down my disease and find a specialists. In particular I have Bartonella which is a co-infection causing neurological symptoms. So I have been on antibiotics for 8 months and have had some improvement in my symptoms. The type of antibiotics that works depends on the patient, so it is a trial and error with monthly feedback to the doctor. Also taking alot of probiotics is part of the treatment. But the key is to find a doctor on ILADS because they are the expert that can help you.
