This. Its probably nothing, but still worth checking out. There is a chance it could be serious, particularly if it is not a one time occurrence.
Err..body parts don't fall asleep due to lack of blood flow. The cells would die without oxygen. Its because the nerves get pinched and the connection with your brain is interrupted. Thats why you get that wierd tingly feeling as the nerves begin working properly again.One time I had one of my legs completely go to sleep. I think no blood must have not been going to it all night because when I woke up I literally fell right down and could not walk. My leg was like a very light blu-ish and I was kind of freaking out.
By the time I got in the shower the blood was coming back and damn it hurt like hell.
