Painful spots appear on my wife's hand

This is the description from my wife: "Red blotch that's painful, turns in to white spot (which also hurts), then the spot kind of bursts and it doesn't hurt anymore. Pretty much one spot at a time. When one goes, another appears."

They appear mostly on her middle or index finger. Started on one hand and now appearing on both.
