What Causes Warm Feeling In Feet But Cold To The Touch?

Thank you, I am very bothered with the feeling that my feet are very hot but are cold to the touch. This cause great discomfort, the worst a bed time. My family doctor has been treating me for neuropathy with gabapentin 600mg 3 times a day, helps a little, but unable to ware closed in shoe or put feet under blankets. I asked him about seeing a PVD, he said to do it if I wish.
