Twice in the last two weeks I have felt a sudden soreness in the mid section of my right middle finger. A few hours later that section became blue but only on the back of the finger. Several hours later the tip of that finger was numb for about 3 hours. It took several days for it to clear up. Now that it has happened a second time I am wondering what is causing this.
