Perhaps this is the wrong forum for this, but it's to do with sleep I guess.
3 or 4 times in the last while I've woken up, having slept the whole night lying on my arm, and it's completely numb. No feeling whatsoever in it. I can still move it, but not as well as usual.
Now, once I stop lying on it the sensation starts to come back and it's back to normal within 30 seconds or so, but still, those few moments when I wake up and can't feel my arm are really scary, and also I'm worried that if I slept on a bit longer I might do permanent damage or something.
Since it's only happened in the last while, I've started to try and make sure that I sleep in a position where my arm can't get trapped.
Has it ever happened to anyone else? And am at risk from permanent damage if it happens too often?
