My Dr. has me taking 750 mg. of magnesium and thanks to Ms.D's reply now I know why! I did not know the connection. It must help with the burning pain, but also helps with constipation when I take pain meds. I have a "TENS" unit that helps and oddly enough a warm heating pad over flannel helps me too. I have yet to figure what sets off the burning pain because I guess I'm fortunate that it comes and goes.
It's all such a mystery - We need a cure!
