Thank You For Your Time. My Name Is Andy And

Thank you for your time. My name is Andy and I have had a strange burning sensation in my feet. I am not diabetic.. my feet fall asleep more readily... and all tests seem negative. My feet flush with red at times... and the only relief is putting them in a bucket of ice water. What could this be? EMG/NCV's are normal.. blood sugar is normal.. and I find that anything restricting my feet like socks can make me very uncomfortable... Any ideas?? Thank you!
