Robyn-I'm glad they were able to find a solution. Sounds like his case was pretty extreme. Mine right now is just perplexing and annoying. I'm hopeful that it won't move beyond that. It's really a very strange feeling, especially in light of the fact that my hands don't feel cold (perhaps because I can't feel them??). I remember the day I damaged the digits...it was a great day of backcountry skiing in fresh snow, but it was probably close to 0 F. That's pretty cold for CA! (OK, I was at close to 10000' but that's still cold for midday!)

I know it's more than just being cold. While I used to be much more sensitive to cold, I've adapted over the years (living in a semi cold place and doing lots of activites in the cold) and really now am super sensitive to heat. Being overheated makes me very cranky; being a little cold is not a big deal. Since I figured out what to wear (duh! they don't teach you that on the sunny coast of CA, which is where I grew up), I can pretty much say that I haven't been miserably cold in a very, very long time (though miserably hot on a regular basis). I think that maybe the wind chill effect on the fingers, even through full gloves, could be triggering it, which is consistent with Robyn's experience with her son.
