wow..all that scares me...the joint pains you describe sound like how I feel. My ana and reumy test came back negative, but I am still going to see a reumy Dr in two weeks. I don't know about
having that gene, but just because you don't have it doesn't mean it isn't spondyloarthropathy (thanks Dr A).
I have never in my life had joint pains or back problems till after I was diagnosed with UC and long off pred..
Good luck and let us know how it goes. I would so much rather be able to treat without any more drugs.
