Celebrex side effect?

I've had stomach aches off and on over the past couple months. The kind that are really piercing, like I swallowed glass. They sometimes last a day, or a few days. I've had one for a couple days now that is just starting to ease up. Since this is listed as a possible side effect of Celebrex, I'm assuming that's what it is. When it happens, I stop taking my Celebrex until it goes away. Of course, this means that I'm in agony. Today my jaw and hands are particularly bad. I was already just eating crackers because of the stomach ache, now it's hard to eat anything at all. I've got a doctors appointment on Monday, so I'll bring it up and see what she suggests.
