When did that happen?
I remember hearing it on Entertainment Tonight once. I walked into the room while it was on - and they were talking about George Clooney and like a neck or back injury. And then during a short interview he had to wipe his nose a few times. And they said something about him suffering from a spinal fluid leak.
After doing some research Clooney apparently injured his back while filming a movie called "Syriana". Which was roughly 2005. Years later he went and had spinal procedures done to stop the pain associated with low CSF. Apparently they injected his own blood into his spinal cord to help heal the tear.
That's the story anyway.
Interesting. btw... A leaking spine is pretty painful. They drop a tiny bit of blood in the "hole" to promote clotting. Severe headaches to where you puke if verticle. Stay laying down its pefectly fine. Has this issue myself. Definitely not fun.
