Lols you're all gits!
@Marzman: Cheers for that dude, despite how common back injuries are its surprisingly hard to find someone else who has been there and done it. I think I'm lucky in that I've had no muscles cut, fused bones or bits added, but I'm definitely aware of what's been done inside and I've already seen a physio regarding some basic muscle exercises, will definitely keep it up after reading what you've said.
@Dblock: No idea how it happened in truth. I think (and this is my own hypothesis) that it goes back to when I was 12/13 and was playing hockey at school. Bent over to whack the ball, back gave way, had about a week off then it was fine. Fast forward to 5 years ago and I literally woke up one morning in absolute agony, didn't do anything to set it off at all that I can remember and had been in pain ever since. Was quite funny in hospital, it must clearly be the kind of thing they see a bit often in a certain type of person, as they kept asking me if I did it playing rugby or football: A less talented player of either sport you couldn't hope to find!
Not very comfortable this morning, so am dosed up on the good stuff again
