Does anyone else have fingers that seem to arch slightly between the middle and third (furthest/last) knuckle? My fingers are straight and work fine and all, but nobody in my family and nobody who climbs (that I know) has this. I don't remember if they were like this before I started climbing. Been climbing/hangboarding/gym bouldering for going on 5 years now. Is it even remotely normal? Internet searches haven't yielded anything.
