Hi Shastagirl79, your symptoms sound similar to Fibromyalgia. With it being 7 years since your hysterectomy, you probably have already gone through menopause/hormone treatments? It isn't just low iron that causes your symptoms, although it would help to take an iron supplement. I'm no doctor, but I am Fibromyalgic and these are some of the symptoms of that.
I've been dealing with this for a long time and I don't want to be negative, but it is hard to deal/live with and information is one of your best friends. At least it would give you a direction to look in. I hope the best for you and hope your iron can be fixed easier than this other would be, but there's even hope there.
