Hi Robyn. I am sorry you are still not feeling well. I honestly can't answer your questions, but maybe the folks with fibromyalgia can. I know you want this figured out today, but maybe you just need to be patient, and work with the professsionals you have consulted to try and sort this all out. It seems to me not so important to have a 'label' for it, as much as it is to find activities that make you comfortable. You mention thyroid nodules? Are you hypo or hyper thyroid? Is it being corrected? I am hypothyroid, and I had bad carpal tunnel before it was optimally corrected. I don't think you should worry you have some other terrible disease, but you should be aware that an out of whack thyroid can cause a lot o f diverse symptoms. At one point they also thought I had fibromyalgia, but that all went away when I got proper PT and on the bike correction for a leg length discrepancy. SO sometimes lots of little things can also contribute to diverse symptoms and you are probably the only one that can sort it out. I am throwing this all out, not that what casued my problems is causing yours, but the idea that sometimes it can take time to sort out multiple small things. The best is probably to focus on one problem at a time. I would start by dealing with the thyroid nodules, and be sure your thyroid is either functioning well, or get on thryoid hormone replacement therapy. It doesn't work right away either, it takes about 3 months for the body to adapt to a dosage change. Good luck, stay strong and positive, and you'll sort through this all!
