What Causes Bleeding And Pus Oozing Lump On Leg?

I had this lump on my leg, at first it just had a green small tip,
I figured it was infected so I took tweezers and removed the green part, then cleaned it with a cue-tip.
This was about four days ago. Three days went by, and it seemed fine until last night. Last night I decided to clean it again, I noticed a white puss substance in it this time, I squeezed around it, and blood started to pour out. As-well as the white puss. I figured it was fine, I poured some peroxide onto it to clean it, and placed a large band-aid onto it. This morning, I woke up and there was blood running down my leg, from the wound. About once every one-two hours blood just pours out of it. Along with the white puss. When it first happened, and it was just a bump, it had a hard spot, like a square under my skin, but as it bleeds out, it goes down. Now I can see the actual wound and it has on-top of the bump three holes, in a "Triangle" formation. I am only 16 so I am not at all sure what this could be. I don't remember being bit by anything, but what worries me is the blood. Each time it drains, I got through 8-10 Cue-tips full of blob's of blood. Any idea what this is? Also, the holes are pretty small, but noticeable.
