Have you ever sat down with your legs crossed or your arm in an awkward position and you feel a tingling sensation on just your arm and your leg may just be numb. Anyone know why this happens?
it restricts the bloodflow to the part of the body, therefor making it numb.
yea this happens to me alot!!!
Oh that happend to me a few nights ago. I was sleeping on my left arm and woke up in the middle of the night. My arm was completly numb, no feeling and I couldn´t move it. I have use my right arm to move it. But it was a cool feeling when the blood was rushing back in the arm…
I thought that it was not the bloodstream but the nerves. It is not dangerous. I have it a lot. Sometimes when I wake up I can’t feel my intire arm, it feels cold and I can’t move it. But it never stays long 
I’m pretty sure that it has something to do with the nerves. If you stop the bloodstream your arm can fall off 
Your arm needs blood.
I have this alot, very weird experience. It isn’t blood, since when i feel my arm, it’s warm.
Ya somtimes when I wake up I could not feel my hand/arm at all. It’s really cool and odd 
. What I’m talking about is that when you sit on the floor or something to watch a movie (you’d get this at school from like elementary or middle school) and you get up your leg is numb X D.
I have been under the impression that it is because of blood flow for a long time.
I am almost positive that it is.
