last night when I was sleeping, I think I was too tensed? My
left shoulder had that "pulled" feeling.. damn pain. I woke up and
had to massage it a while, then i can move my shoulder.. Or perhaps
I was lying on my left shoulder too hard then blood don't
circulate?
Possible.
I remember flipping through this medical book in the nursing
school's library once. The book lists a few really
interesting cases that has passed through the Emergency section of
various hospitals. One of the cases involved a young bloke in
his early 20's who had a drinking binge with his buddies, got
stone-cold drunk, passed out on the couch, not realising that he
was sleeping ON his arm in a bad position and woke up hours later
to find his arm totally limb! In the end, they had to
amputate that arm because the blood supply to that arm had been cut
off for about 6-8 hours and the nerves and cells had become
necrotic from hypoxia (lack of oxygen)!! I remember thinking,
What the... !!! 
and urgently whispered to my classmates to read
the case too!
