sorry to jump in, but i had the impression that
Celebrex was going to be taken out of the market
for several reasons. It is not sold in South America because of that, since people were complaining about these symptoms you metion (upset stomach, etc) and one of them was "bouncing pain".
Amy, did they put you straight on Celebrex, or did you try other mild over the counter painkillers? i suffer from both AS and MS, and i take higher doses of Advil or any other Iboprufen around.
