NOW there are blisters coming to the surface - or showing up - or whatever. I couldn't figure out what it was but dh mentioned the burn and yep - the blisters are where the worst burning was. Weird. There'd been no sign of damage after the initial day or two.

That is weird! I burned my finger the other day.. touched it on a very hot pot while I was cooking.. the very next day I had a huge blister and it itched!
It's finally feeling better though is does still itch with is strange, I've never had a burn itch so suddenly before.
