What, other than Raynaud's, could this be?

Is there anything other than Raynaud's that could be causing the middle finger of my left hand to suddenly turn dead white and go painfully freezing cold, stay that way for about 5 minutes, then go back to normal? It has only happened twice so far but I'm having a little bit of a freakout. Both times I was in my warm house doing some normal little household task.
