I had this problem for a long time. My fingers used to hurt like hell while coding during the winter. Here's a few things I learned:

1. Make sure your forearms are level or downward-sloping so that your hands receive more blood flow. Raise your chair or lower your keyboard if possible.

2. Wear a sweater, and if it has a zipper, make sure to zip it up all the way to your neck. I personally hate the feeling of clothing around my neck but it makes a big difference.
