Ouch! 

I jammed my toenail while playing my Week 3 match. Below are images of my self treatment to drain the blood from under the nail. This was done by heating up a safety pin with a lighter and then poking a small hole in the nail.

 Nail Before the Hole

Hole Made, Here comes some blood, only about 4-5 drops came out. 

Finally what is looked like after it stopped bleeding. To me it did not change much but I suppose there was some difference.
