If you get your dosage correct your posts may become very cryptic :)
I managed to put 2 discs out about 10 years ago, wasn't much fun. I now need to be a bit smarter about what I do. When the results from all the scans came back they indicated quite a bit of previous damage to some vertebrae. It appeared that I had broken my back many years earlier. In hindsight I blame a motorbike and a tree that didn't get out of my way.
