I'm Not Sure
.. When I was around 10 years old I played in basketball team. My friend threw the ball but in so weird direction that it hit my little finger when I was trying to catch it.
After a few minutes my finger started to turn green, it was hurting.. but somehow I didnt go to see a doctor, I just put it in bandage and continued playing, hehehe. But with second hand. LOL :)
After some weeks it was ok but I realized later, after a year that probably my finger was broken, because when I played flute, (there is one pad that must be held with little finger continuously), I was unable to bend the finger it was so stiffen. Hmmm..
