worst pain you can accidentally inflict upon yourself?

Question

for example, hitting your knee or toe or something, biting your tongue? i'd go with biting your tongue, because if usually has a lasting effect.

Answer 1

yeh or biting your cheek coz it swells up and then you cant stop biting it.
the worst accidental pain i have ever inflicted upon myself was when i dropped about a litre of boiling water on my foot, which was only covered by a sock, so my sock basically melted to my skin, before my foot erupted into hand-sized blisters that were about a foot tall. then a couple of weeks later, after having been to the hospital a couple of times and had them popped, i could peel off the skin because it was crispy and dead. it was real nice, i put it in my brothers lasagne.
i didnt, but i should have. or did i.........
