This year I am going to try to avoid injuring myself while climbing. I do indoor bouldering, sport climbing, and am starting trad climbing this year.

It needs to be severe enough that I see a doctor, or prevents me from climbing for a month.

Last year I had two. In one I fell and dislocated my elbow, tearing my ulnar collateral ligament in half (but didn't require surgery), which resulted in about a 3 month break. In the second I had some weird muscle aches on the other arm that caused me to take a break for about 3 months.
