I've only had one injury worth speaking of. What happened is I over-worked my hands on a crimpy v5 route that I tried too many times and I didn't allow myself to rest long enough. The result was a snapped tendon pulley, which is a really common injury. I took a few months off and I'm back better than before.

I have found that stretching before and during climbing, taking breaks and drinking water really helps me. I try not to over-work myself any more, and if I can't do something I'll allow myself to come back to it later. It's so easy to get caught up in the competitive headspace instead of just having a good time.

I broke a little bone in my foot (I think, never got it xrayed, no insurance back then) and fractured my tibia pretty badly recently, sitting in the ER feeling it and gimping around for the next few months I NEVER had a doubt that it was worth it for me. If you are sticking in Ironworks it's not too high a risk. Learn to land well, I did up my last one indoors bouldering but I was really tired, pushing hard and wearing pants with wide bottoms that got hung up coming off. TOTALLY worth it for me,,,,back on the boulder wall today and the foot is starting to streach out again.
The funnest injury was to a friend who slid down a smooth sandstone face about 25 feet on his bare chest and had two bloody nipples afterwards, they grew back but he never tried breast feeding his kid, the kid now climbs pretty regularly grew up healthy regardless.
Iron Works at least used to be a super mello scene and positive attitude folks.

I recently tore the A2 pulley in my left ring finger. hadn't climbed in regularly years and then started recently again. bouldering an easy route and then POP! Talked to someone who works at my gym and he said that that injury happens frequently in the first few months of climbing as muscles grow stronger faster than tendons and ligaments do. Now i gotta wait a while...
