my feet are driving me crazy. One minute they are burning and tingly and they are always very sensitive,e.g. if i have the tiniest pebble in my shoe and I take a step I almost fall to the floor in pain, at night my feet are freezing. My feet and the bottom of my legs feel like I have been on them all day achy and painful. I have to wear a good supportive walking shoe at all times, I can't ever go barefoot because it hurts too much. Thank you, Mary.
