Apparently my hand decided to punch a wall today on my way out from my hairdressers. Walked out the door, turned the corner and "smack", my hand found the smallest bit of the wall sticking out. Got a sore ring finger now.
Ugh!! Something similar happened to me about a couple of months ago. Also hurt my ring finger, and and to this day it's still sore. So, get some ice and put it on your hand, and I wish you the best!!!
