Blood tests can come back negative for RA. But that in itself doesn't mean you don't have it.
I actually don't know where you go, ESPECIALLY if you have to deal with DR.'s under or should I say in a H.M.O. plan. I noticed to way my Dr. treated me when I had Medi-Cal. I got EXCELENT care, unfortunately, a few months later when CA made it MANDATORY for some to join a H.M.O. (like me) the same Dr. went from caring & concerned to not helping me at all! I changed Dr.s & found that it was the same with each one. Strange though, anytime I needed help & had to deal DIRECTLY with the HMO I never had a problem! It was the Dr.s themselves!
Back to what you can do, I want to warn you, BE VERY CAREFUL with ANYTHING prescribed! I don't trust the FDA or Big Pharma. Sorry, but the FDA & Big Pharma have a VERY SERIOUS CONFLICT OF INTEREST!!!!
If you can afford a "Natural Practitioner or Holistic Practitioner" there ARE 100% SAFE & natural "meds." You can also probably find a M.D. that practices "natural medicine".
Unfortunately, most insurance doesn't cover these types of doctors.
There are also publications that you can read to "RESEARCH" meds & their DANGEROUS side effects.
As for your pain I have found that SWIMMING works wonders & it's the ONLY thing that I can do without ending up in worse pain. I have other problems besides RA.
