Fingers already injured or just on the edge?
I have been climbing indoor for 15 months. Generally 3x a week for the first 13 months, 2-3 hour long session. Recently I have increased that to volume to 3-4x a week (every other day) for 3-4 hours. Usually about an hour of warm up into limit bouldering attempts. My grade has risen extremely quickly in the last two months, but I know this is unsustainable and I may already be injured.
I am 6'2.5" (189cm) and weigh 160 pounds (72.5kg), if it is relevant.
Yesterday I went to try hangboarding at the beginning of my session and discovered that a 30mm deadhang for 10 seconds took real effort. I could only do a 25mm edge for 8 seconds.
I was able to do 3 pull ups on a 17mm edge just five months into climbing, so ten months ago. I went to try it again on the same doorframe recently and was too scared to even lift my feet off the ground cause it felt very uncomfortable to do so.
I never notice any pain when climbing, or outside of it. Even after the terrible hangboarding results I hopped on the TB2 after an hour of easy climbing and was climbing V4 classics and very close to V5 classics (40 degrees).
I am going to take the next two weeks off, at minimum, of hard/board climbing and just focus on footwork on easy problems. However I am a bit worried that my fingers are already injured and this won't be something I can quickly bounce back from.
