My right foot (only occasionally the left) gets and stays extremely cold. I am not diabetic. This lasts for hours on end and almost daily. It hurts like when you're out in the snow too long only this happens without cold exposure. My foot is not red, or blue, or purple, or any "off" color. I put on socks and even fuzzy slippers at home trying to warm it up. This has been happening off and on for short periods for several years, but it never hurt or lasted very long. Today my right forearm is having the same symptoms.
If ANYONE has ANY ideas I would be so thankful to hear them. This is driving me crazy!
