Help. Every night I wake up between 2-4am the bottoms of my feet are burning, just as if there was an iron touching them. Last night I was awake from 2.40 until 3.40 I stood in cold water to cool them down and walked around for an hour. Is there anything I can do to help myself. I have given up anything with caffeine in it. Last night I took para/codeine to help get back to sleep. Any help appreciated.
