Having an annoying skin tag on my back which I could not treat myself without impossible contortion, my G.P. gallantly offered to assist with his famed 'Cryogenic Clinic' available on Saturday mornings.
Halfway through the treatment he stepped back and asked (with some degree of irritation) 'Well, do you want this done or not ?'
Having liquid nitrogen applied to my skin at close to absolute zero (zero Kelvin for afficionadoes of the art) had caused me to move a few millimetres and Dr X is used to absolute compliance on his Saturday morning tort... I mean treatment ... sessions.
The problem is it 'burnt'.
Please note, it did not 'freeze'. My skin did not become a solid. Had it done so, my nerves would have transmitted no electrical signals to my brain and I would have felt nothing.
I have thought long and hard about this from a physics aspect and Googling has done nothing for me at all.
It is a 'burning sensation' but it is not a burn.
I winced with pain when the liquid caused a _______ sensation.
