Mobic Shoulder Impingement, Heat Rash, Running a Fever, Heat Buildup, Hot Flashes

I was taking mobic 15mg for 2 weeks for arthritis and shoulder impingement. After 5 days I began to have hot flashes and developed a heat rash on the back of my legs from the heat built up from sitting in a chair. I called the doctor and I was advised the mobic was not causing the problems and to continue taking it. Near the end of the second week of taking mobic, my skin was noticeably hot all the time (I was not running a fever). I could not sit or lay down for more than 10 minutes without the heat buildup getting to hot to bear. The last night I spent standing up under a ceiling fan to keep from getting uncomfortably hot. I stopped taking the mobic and symptoms began going away within 24 hours. The mobic worked much better than the naproxen for pain management, but the side-affects were not tolerable.
