Roxette,
I hope you don't have ankylosing spondylitis, because Crohn's is enough to deal with!
My father and brother both have ankylosing spondylitis, but no Crohn's. I have Crohn's, but no ankylosing spondylitis. As Keeper said, both are auto immune disorders, and they are related. My brother has had excellent results with Enbrel. He injects himself with it every week or so. My dad has done well with Celebrex. Please keep us posted on what you find out.
