Tonight I was inside my house making dinner and my left index finger and middle finger went white and numb for about 15-20 minutes. I had a really hard time getting them back to normal - it took holding it in front of the heating vent in my car for 10 minutes. My concern is that I cut these same two fingers about 3 weeks ago. Since then I haven't really had any problems, but the fingers have gone numb very briefly maybe two other times in the past week.
