Why do my feet burn and get really red and hot when I rest them? It is so uncomfortable when trying to rest or sleep. I had brought up Raynaud's but my Dr just kind of pushed it aside. I do have psoriatic arthritis and have been on low dose of prednisone. Could that be it or something with my nerves b/c of the auto immune disease? I am really in need of relief and the only way to get it is to find out myself!
