I am a little worried about hand problems in later life.
I used to box a lot, up till about a year ago, dislocated both thumbs a couple of times and fractured a few metacarples. Never did any finger or major knuckle damage that I know of though. Always kept my hands well wrapped. They did ache like hell after some long sessions on the heavy bag though.
Just thinking about taking it up again as I miss being that fit. Worried that it may have longer term implications for the bones in my hands.
