Hi, the concept of pain returning after being relieved is called "rebound." I get hissing and ringing in my ears when I take Ibuprophen (sp?) like Aleve and Motrin. I also used to take Excedrin at least 4 times a day, and that caused the tinitus too. I had to find new doctors when we moved here to CO. I told the doctor that I got a diagnosis of FM right before I got the diagnosis of breast cancer. I said that I was better able to accept the BC diagnosis then the FM because cancer can be determined by xrays, etc. and FM seems to be a phantom condition. She said that cancer was actually easier to treat then FM. She was willing to prescribe pain meds on a regular basis and I take them on a regular basis. I've let go of the concerns of addiction because I don't increase the dose, and the meds do not lose effectiveness for me. It works for me. This morning is a good example of FM. I woke up with aches and pains all over, and I did nothing strenuous yesterday. Unique, aspirin can be so corrosive to the stomach and intenstines. It kicks in faster when combined with caffeine. Caffeine tends to make things worse for me. Research ignores FM because it can't be read with a blood test, and because more women than men are diagnosed. Now, if the reverse was true, then money would be spent on research to improve the quality of life for men! LLL
