Hmm, interesting read. I'll have to check out WebMD in the future. This is kind of an odd case though as I tied an ice pack to my ankle for 8 hours. It pretty much froze for at least three of those.
I have no idea if it changed colors/turned white etc. since it would have had time to thaw underneath the ice pack as it eventually warmed up. (those 8 hour ice packs rock btw).
Now it's just sore as hell and swollen up. Oh well, probably nothing. Figured we might have a doctor in the house somewhere though who'd seen this before.
