This has happened a couple of times recently, not to all but to two or three fingers. It is also just at the ends, like the last joint to the finger tip.
I think its because they have just got very cold, and I have always had chilblains on a couple of toes since I was little. Maybe its a circulation thing?
I had it last night after DC school carols and as my fingers recovered you could see the blood flow restored so was so eeeuuuuwwwww it was fascinating! When they are like this, they feel like ice to me, but not if you touch them ( at least thats what DH said lats night)
I imagine prevention is the key here, I'm not sure what else could be done.
Does anyone else get this?!
