I had this hard pimple under the skin, for a while now, it was coming to the surface, then just a few hours ago it rupture, i felt it leaking so i went to the rest room to see, all i saw was the puss, so i wipe it, then because it was still leaking i got a q-tip and gently sqeeze around the area. Lots of liquid came out yellow ish, and also blood, then i put rubbing alcohol on it, but it is still hard and purple color.Its it normal for a pimple to rupture on its own?Help plz 
, it stings
Hopefully all the puss got out of it, because the inflammation should go down within a couple days then and it can heal up. I guess they could rupture on their own, never had that happen personally. Wouldn't hurt to apply some BP on the are so the bacteria doesn't spread.
