Sounds like the meningitis type of symptoms that I get with Lyme from time to time. It's truly miserable as very little will help it, other than time.
It's always good if you can get tested to make sure it's not something else, but as has been said, most of the time it will be Lyme and company.
BVT = Bee Venom Therapy
Rocephin (Blue misspelled it) - is an abx that is often used to treat these infections.
Biological DDS = A different kind of dentist, one that understands how the mouth is connected to the health of the whole body. They will use less toxic things to help repair damage, including looking for infections in the mouth. I'm sure I didn't explain that well enough though! Hopefully, this link will help:
