Joint pain

C
How do you deal? I've been to several rhumetologists and no one has really come up with a definitive diagnosis. The last doc I tried did tons of tests and decided it must be RA, despite all inflammation markers being negative. I'm allergic to NSAIDS and before I was they didn't help. Steroids don't help. Are there any foods or supplements or other remedies you've found help?  Heat and immobility works sometimes, but I need to be able to function at work.
