Why do my feet get really hot at night?

Could be: Neuropathy. There are many causes of neuropathy. Do you have any conditions affecting your back? See your physician.

Well there : Are plenty of guys with cold feet so this may be a good match. On a more serious note- any history of low back pain as this may be a cause. Is this a new problem? How long has it been present? There are localized nerve entrapments like tarsal tunnel syndrome which may be a cause, and there is an isolated condition of "burning feet syndrome". If its isolated alpa lipoic acid 1200-1800 mg per day.

You may: Have neuropathy. I suggest you discuss this with your dr.
