Back when I was having chronic back pain problems, I often found it helpful to fall asleep upright on the couch with the legs extended and my right arm hanging over the side of the couch. Apparently, I managed to injure some nerves in my arm by sleeping on them too much because I woke up one morning unable to feel most of my arm and hand. I went to the ER, panicked. The doctor told me it was called Saturday Night Palsy because generally, drunks get it after becoming intoxicated and leaning on a nerve too long (brachial? radial?) - like falling asleep on their arm on a park bench. It took about 3 weeks for the feeling to come back in my arm. Strange to end up with a "drunk's disease" when I don't even drink.
Just curious if anyone else has ever experienced this.
