Awhile ago I noticed these weird black holes in my butt crack, they kind of looked like really big and deep blackheads. Me being curious, I squeezed them and clear-white pus came out (sorry I know really gross). The other day I noticed my butt would hurt when I would lay down, so I checked it out and there was a bigger lump than normal. I treated the bump with a zit cream and it went away, but the black holes won't go away. I have had them for quite a while. What the heck are they? Please help me!
