Sorry to hear that!  I hope your get it healed up and have full use of it soon!
  I was in a hurry and sawing with a cordlesss circlesaw, and i hit my finger about a year ago.  It went pretty deep, but other than a scar, and no feeling in that spot, it healed fine,

  Then again, it wasn't near as bad as what you have described...
  It made me a lot more careful when i'm using that little saw!!
