Hi Ditter, to ansewer your quistion I have had fibromyalgia for over fifteen years, I also have copd , and of course the back injury, and your right some days are great and some days are the worst life can bring, but Ive learned to puch through the tuff days and make myself continue doing what has to be done. The Doctor told me to stay active and this would help. I take motrion, and pain meds, and stay away from cold as much as I can, for some reason If I get cold I have more pain. Penny
