18 months ago he broke his finger and now when the weather gets cold it turns white

That's the coolest thing. Like 'color changing finger, just make it a bit cold.'

ET GO HOME

I thought it was the pointer finger and was all like
Why is it so short?
Where's the thumb?

My mother has this thing which makes her fingers white like this at random times and she can't feel them when it happens , it's annoying

It's called Raynaud's disease. It occurs in people with poor cirulation in the cold. I have it, and it's extremely painful in the fall/winter. When I come back inside after being outside for an hour or two, my fingers are numb...and then they burn and sting sooo bad for like 10min as the blood forces it's way back into them.

It is goddam painfull, I once dislocated my ringfinger and pink and now this happens every slightly cold day
