Welcome -- sorry to hear you are suffering.
Lyme symptoms vary from person to person for a variety of reasons, so if your doc is telling you that you don't fit the diagnostic picture, then I would consider getting a second opinion from a Lyme specialist (not a rheumatoid arthritis [RA] doctor, as your current doc is).
Note that some RA docs can take a more progressive stance on diagnosing and treating Lyme, but many may not. Emailing to ILADS [dot] org's website and requesting a referral to someone near you might be a good step. Also look up TXLDA, the Texas Lyme Disease Association, and ask for a referral to a Lyme specialist near you.
As tho Lyme isn't bad enough, dealing with MDs who do not understand Lyme well is something to avoid. Let us know how we can help -- best wishes to you --
Ditto what Jackie said. I had similar symptoms when first very sick so I would see a LLMD. Lyme literate Dr.
I like emailing ILADS.org and asking for names. Unfortunately there are a few Quacks out there calling themselves LLMD. If they have been trained by ILADS that is the best.
Good luck
