Why do my feet feel cold yet they're warm when I touch them?
Neuropathy effects the sensory nerve endings, the cells at the end of these nerves at the skin level to die off and recede deeper into the tissue. The nerve that controls the sensation of cold itself is not dead, just the nerve ends, so the nerve will continue to fire without any outside stimulus causing the abnormal sensation of cold, when the feet actually are not.
Why are my symptoms worse at night?
Neuropathy causes damage to the nerve ending, but not all of them in the beginning so you still have a number of normal nerve ending. During the day when you have your socks and shoes on, trying to do normal activities you stimulate the normal nerves and it overrides the abnormal sensations, at night you take your shoes and socks off and the stimulation to the normal nerves is not as strong the abnormal nerve endings deeper in the tissue become more apparent.
Why do I have pain when my feet feel numb?
Different types of nerve endings produce different sensations at the same time, one type will produce the numb feeling, while another produces pain. If both nerve endings are affected by your neuropathy they both can fire at the same time, producing the numbness and pain at the same time.
