Funny! I did just the reverse! Took celebrex for about 2 years, then started having very severe lower abdominal pains that no one could figure out! Finally, after reading the side effects, decided on my own to stop the medication, and the pains finally stopped. Then, when I got bursitis in my hip, doctor wanted to prescribe celebrex and I said, no way! So he put me on relafen, and I don't know if it works because guess what? Started getting stomach pains again! I was only on it off and on for a few weeks when it started. I am having quite a bit of pain everywhere right now, so decided to give it another try tonight and for a few days and see what happens. It really stinks when NOTHING seems to work!
