Now that hurts!!

Who on earth goes to a very sunny country and ends up with ICE burns - yep that'e me - in an attempt to speed up recovery on my knee (see blip of 4 days ago) I put the ice packs from the freezer and directly applied to said knee - after 30 mins I could not feel a thing - removed packs to find skin frozen solid - it is now only just starting to thaw out and I do believe I have FROST bite - boy does it hurt!!
