Thanks for the feedback, everyone! I didn't know that others felt the painfully numb, icy sensation too because I read so much about the burning. I had a lot more of the burning back in the beginning, when I woke each morning my leg looked & felt sunburned. I still get the burning but not as intense. I also get some odd sensations like my leg / foot will feel wet when it is dry - I go through a ridiculous number of socks each day because they feel cold & wet to my foot LOL :-)
