If you’ve already done the recommended anti-biotic courses for Lyme, you’re basically probably looking at symptom management for your post-treatment symptoms (potentially due to PLDS).

To put it another way, a Lyme expert may help, but in the short term, I’d look into symptom management options with whatever doctor you can get in to see.
