Celbrex is horrible I was given it for my AS and it works just as good as any standard NSAID... I am also on steroids and was just given a script of tramadol and I still am in moderate pain but its better then nothing. Good luck on your diagnostics, do not be afraid of going to Clinics out of city or state for second opinions. State your frustrations at a different clinic maybe you will get a better answer. Good luck.
