Hi everyone: I had been taking Bextra for arthritis pain in my knees and it worked great. This morning I took a 7.5 mg. Mobic. It didn't give me any pain rellief. So, I'm thinking maybe I need to take it for a few days to see if it works or increase the dose to 15 mgs. I'm going for Acupuncture this afternoon. I hope it helps b/c I can't stand being in pain all the time. If not, I'll have to call my Orthopedist and ask what else I can try. The Drs. out here are all afraid to prescribe narcotics, so I know that's out. Any suggestions or advice? Thanks.
