Dear Pain Peeps,
I am looking forward to my annual bath in February and still have fond memories of my last one...but one memory I have is not fond.
Not being used to keeping clean, when I last filled the bath I ran the water too hot.
When testing for the temperature I placed my hand in the bath and then suddenly retracted it in pain...but then....a few seconds later...I got a second ' Hit ' of agonising nastiness !!...why does this happen ?
Do ewe know what I mean ?..have I explained it Ok ?
It's like a wave of pain....The 'instant ' pain of direct contact with the hot water and then another wave of pain just a few seconds later.......

I don't think I have ever experienced that and taken note of it..Will have to pay more attention..

Not sure if it is so much to do with pain (unless its psychological) as to do with heat damage particularly - I think probably the initial shock of the heat is a direct sensation, while what follows if probably the continuing damage to the skin (i.e. the first pain is an early warning alarm, while the second pain is a damage control signal).
What might be the case, although this is something that I have not experienced myself, is that the initial shock may protect you from the pain a bit, and as the shock wears off you may sense more pain. Another possibility is, as I suggested, there may be a psychological element that as you become more aware of the pain with time, so that awareness raises an expectation.
My preference is for the first theory, but that may just reflect the fact that I tend to have a fairly high pain tolerance (although maybe less so now than I had in my youth).

With regards to shock, all injuries can and mainly do lead to some degree of shock. The symptoms may not present themselves as what you would associate with shock, but when treating someone you always assess for shock.
the symptoms can be: rapid pulse, pale cold or clammy skin, weak and dizzy feelings, thirst, nausea, rapid shallow breathing...I would suggest that a common symptom of shock would be the lightheaded, dizzy feeling.
Now on to burning yourself in the bath, Neil. I am a bit rusty on this as i don't have to treat any burns at work (designated first aider). If i remember correctly, for burns you should pour cold water )or other fluids such as milk) over the effected burn for at least 10 minutes. The pain you feel is the actual burn and damage caused to the skin, you cool the area with water for those 10 minutes as this is how long it takes to "bring out the whole pain" or something like that.
like i said i am rusty on burns, but I'm sure Chris or someone will have a good answer.

But one of the effects of shock is the release of endorphins (which is probably part of where the light-headedness comes in), and this can suppress pain.
