Holy cow!
Hmmm. My friend Roddy had the same thing happen to him. He woke up and his back seized up. The pain from his back went through him and he thought he was having a heart attack. His wife called the ambulance, the whole bit. They took x-rays and all that and told him it was a spasm.
One of the things he said attributed to this was that his mattress was really soft. Too soft. It really messed with his spine. He was on some muscle relaxers and he was fine.
Hang in there, Mr. GD.
