An overview of some injuries and recoveries:
In 2005 I took close to a 40ft whipper on a sport route at Torrent Falls in Red River Gorge. Somehow in my falling my arm got caught between my knot and my safety knot in the rope. When the smoke had cleared and I was lying limp at the end of the rope, my partner thought me dead. The "loose" loop in the rope had caught and stretched tight enough to squish my right triceps, permanently separating it into two sections connected only by scar tissue.
The dreaded injury that had nothing to do with climbing but keeps you out for months: I was skiing in the trees at Beaver Creek and hit a buried rock that sent me superman-ing into a boulder field. While my brain was screaming "Protect the head", I stuck my arm out to brace for impact. My right shoulder received such jar that I couldn't use it to climb for over two months...and I tried. And I kept hurting it. It took nearly six months for my shoulder to heal completely, though I was climbing hard before it did. Lesson: Stop doing stupid things that impact your climbing. Side note: get health insurance!
The Back Breaker
"Onsight it! You can do it! It's a Jughaul!" Although I was pretty inexperienced at Trad I thought, what the hell, this one is just my style. I jumped on the Kloof in Eldorado canyon, and without thinking about my gear placements or the fact that I should think about my gear placements I started swinging up the overhanging route. I was sport climbing. I had no worries. I got a little bit off route then made a big throw for a hold. "Eh, not good enough" I thought, and I let go. I LET GO! Pop! Pop! In 30 feet I'd placed only two Camalots, and both of them failed. I hit the ground, amazingly on the flat ground between two large rocks that would have wrecked me.
