Got a papercut slice on the inside of my pinky finger, right at the main bendy joint (fretting hand). At first I blamed my pull-up bar, but I think it’s from the bass G-string. Hits right at that spot when little pinky tries to reach other strings… gah!
Put some liquid bandage on it. Almost good as new.
One time I spun around while I was practicing and accidentally knocked a bottle of beer off the table. I got a small cut on my hand while picking up the broken glass. I was so devastated about the wasted beer that I was unable to continue practicing. Does this count?
