I imagine cauterization wouldn't be very fun. x: Kind of a cool concept, though!
On the subject of wounds (interesting subject haha), I recently woke up with cuts that weren't there when I went to sleep. That was confusing. I still don't know where they came from. ?_? At first I thought they were just marks from my arm being against something, but then they didn't go away.
But yeah I've never had any serious injuries. Had a bit of flesh cut off my foot by glass, accidentally sliced off skin (maybe flesh, as well) from my ankle, etc. And too many more minor cuts to be able to count them haha.
