Back Injury

Anything below ten grand in damages is going to be hard to find an attorney to take your case (because most PI attorneys work on contingency). But I'd say there's totally a chance that you could have a case...him having a duty or something.

If you were climbing, how do you know he/she was "inattentive" ?
Have you climbed with him/her as a belayer before ?
Have you watched how he/she belays others ?
What type of belay device was he/she using ?

Even if your belayer was distracted, you should not have necessarily hit the deck. Bad belaying technique is endemic in some gyms that I have seen.
