My insurance company will no longer pay for Celebrex. What drug will work as well as Celebrex does? I have tried diclofenac, mobic, and all the generic celecoxibs but none work for me. I have arthritis in every vertebra of my spine. With Celebrex, I have no pain whatsoever and complete freedom of movement. Without it, the pain is agonizing and debilitating. I have been taking Celebrex 200 mg twice a day.
