Can you put your injured hand flat on the ground as in a pushup?
Can you hang from a pullup bar or do pullups?

"And for crying out loud. Don't go into the pain cave. I can't stress this enough. Your Totem Animal won't be in there to help you. You'll be on your own. The Pain Cave is for cowards.
Pain is your companion, don't go hide from it."
