I have found a very simple solution to temporary relief of stinging, tingling, irritating numbness to my feet due to nerve damage from Diabetes II. I simply put on wet ankle socks when going to bed! I don't know why or how, but as long as the socks are wet, I sleep like a baby; the tingling and the irritation in my feet literally almost stops immediately. Yes, once the socks dry out, they need to be re-wet but this beats having to buy expensive medicine. I hope this helps somebody else!
