ssr my RA factor is high!! I've been on Daypro (anti-inflamatory) for some time now due to whatever this is getting into my lower back/spine and my left knee...I was tested for Reiter's but the Rhreumatologist said he doubted it because I didn't have an HLA-B27 gene...or something like that. SSR could you please email me at ?? Sounds like we may have a similar condition...and you seem to know your shit!! THANKS.
