I have type 2 diabetes and sometimes when I go to sleep my toes feel hot and cold at the same time. Well I was reading about vitamin E and experimented on myself. I read how it's good for nerves and blood so I took a few gel caps and punctured them with a needle and laid on a good amount on all my toes. The pain went away in a couple minutes. If anyone has this problem give it a shot. I think it's bloodflow personally since it feels like they are falling asleep like when you sleep on your arm. I just figured I let everyone know what I found worked for me. Hell look up vitamin E and "Not a vitamin site but a respected medical site" and see the many things vitamin E does in the body. You can just buy the oil and spread it on but I have to wait till I get my check but most haircare and skin products for looking younger and being healthier even expensive one have vitamin E as a major ingredient because it works. If you use gel caps or oil make sure it's this type of vitamin E the articles said tocopheryl is the type that absorbs and works best.
