I sliced a 3mm place on my fretting index finger, almost so small as to be non-existent.
But it hurts like hell. Every time I scroll the mouse, it lifts a little tag of skin.
Playing guitar hurts. It's been two days and it still hurts.
I mean, it's not like I stabbed myself with an ice pick.
If it had been a 5mm cut, I might have slipped into a non-reversible coma.
