Way back when I sliced my thumb to the bone with a fillet knife while working at whole foods in the sea food department, I've never bled a river of blood before, it was pretty crazy! Then I had to drive myself to the clinic and get stitches. That was a crazy day! When I got there they had me put my arm down then they tied off my thumb and injected a numbing agent into my knuckle below the tourniquet, the knuckle swelled up to almost more than twice it's size! It never healed together properly so I have a little indention in my thumb, but nothing too severe, I didn't even go back to get the stitches removed, I grabbed some dikes and clipped em and pulled them out...only problem with that was they ended up being scabbed into my finger so I had to rip them out...lol slightly painful.
I hope you got yours taken cares of properly, I've had those types of cuts before, a lot when I was a little kid whittling wood trying to be my Grandpa lol I've taken almost all the skin off my my index finger doin' that haha
