Itchy hands & sore ears.. Why?

[Calluna]

Since having DS whenever my hands (palms and pads of my fingers) and feet get really cold, ie if I'm holding a drink straight out of the fridge for a few mins or on a particularly cold day, they get really itchy! It's a stingy kind of itchy not just irritating.

Also my ears - inner and outer- sting really badly (like a bad earache) when they get cold. This is always happened though, nothing new.

Any idea what could be cuasing both these things? I'm really over it and now that it's winter I feel I really need to do somehting to about it.
