or elbow, etc, etc. Why does it hurt more when it's cold?

i dont know... i was climbing down a ladder and it slipped and banged my shin pretty hard and i wanted to shoot someone

I would suggest vasoconstriction would have something to do with it.

I was wondering that myself. However, vasoconstriction reduces the blood supply and, as far as I'm aware, that causes numbness rather than increased sensitivity.

I don't know, and I'm not even sure it is true that it would hurt more in the cold, but. if it does, I could take a guess! When it is cold, you reduce the blood flow to the surface in order to preserve heat. As there is only a thin layer of tissues over your shin, reducing the blood flow will reduce the reduce the small cushioning effect that that tissue has, increasing the pressure on the nerves etc

Oh Carol, I am but a fool - I should have worked that out for myself. Thank you. It sounds very feasible.

aye, vasoconstriction

Yes indeed, JnA. I hadn't considered the aspect that Carol mentioned. I apologise.
