Hi, I have been diagnosed with this after 4 months of severe & crippling problems. I am still not clear what this means...does it mean possibly 1 or more of RA, AS, & a few others? Originally everyone thought RA & Reactive. I have the B27 gene and AS is in my family. I have had severe joint problems with knees, elbow, jaw, wrists, hips, SI, lumbar, spine, shoulder, neck etc. Had a lot of relief with high doses of prednisone but get flairs when going below 20mg. Need to go low this month to 5-7 mg and am on 6th week of sulfasalazine, with no improvements noted. Am told Biologics is next treatment in 6 weeks if no improvement. This whole thing is shocking, am doing good considering, but am really wondering if I will ever get back anywhere near to my old life re activity, energy. I was transformed almost overnight from an active 52 yr old to someone that is 100 years old regarding mobility of a healthy 100 yr old. Am following the Inflammation Free Diet, taking a zillion supplements and drugs.
