That Looks painful ...
I cut my ring finger on a saw 20 years ago, almost severed the connective tissue just beyond the knuckle 3 stitches if I recall and a half cast I had to wear for 3-6 weeks. I was bit by a ground hog when I was a kid right on my pointer finger just beyond the knuckle again. I had a habit of picking up wild animals and bringing them home...a hatchet cut on the other hand.
The one that worried me the most was when I was lifting an overhead door at a previous job and the top came off the tracks, came down and about knocked me out, lucky for me apparently I have a thick head lol
