I am having a lot of trouble, I don't know if it is related to my back, but my shoulders ache a lot, and then my forearms started "falling asleep" when I lie on my side. Then my knees got swollen, and, worst yet, the bottom of my foot fell numb, and won't get back to normal. I went to an "ask the Dr" site, and paid $35 for a foolish answer, now I am trying here. Anyone? Thanks.
