Alright .. I know there have been a hundred or so threads on the topic, but this one is slightly different.
Twice in the last 2 years, I have injured the knuckle on my ring and middle finger on a crimp. I'm pretty sure I wasn't warmed up enough both times. Last year, climbing with Pinky and Eff I was on an overhanging climb, feeling fine, not struggling, and hit a good hold an literally POPPEd off the hold. My Knuckle popped, not my tendon. I'm almost positive it was the knuckle. Anyway the knuckle swelled slightly, and was stiff and painful for about a month.
I'm pretty sure that was my left hand. Now, climbing a vert wall on crimps, going to a good hold with no feet, the same damn thing happened on my right hand. POP. Here's the rub, both times I was just getting back into shape after not having climbed in a while, like close to a year, and before I took anytime off, when I climbed 3-4 days a week and did pull-ups on my rest days, I NEVER had an injury outside of some tendonitus in my elbows. WTF MAN. I know I'm old an' shit but can I just climb something harder than V4+ without my knuckles exploding?
