Burnt my arm last when stirring some soup, I had had the gas on too high and it splashed out the pan. Sat with an ice pack on for the rest of the night after spending an hour with my arm under the cold tap.
Consequently wound up with 2 blisters, 1 considerably larger than the other as the blister popped. So I have this lovely crusty scab that is lifting around the edges and I can't stop picking at it... I'm drawn to it. I want to pick at it.
