My dermatologist says these cysts are not "ick" but more closely related to excess skin cell production. At least until infection sets in. He also says that draining/squeezing them yourself often is not long-term effective, because they have a sort of skin, which if you leave it in creates a pocket and it will be back some time later. He uses a scalpel to open it up a bit, tweezers to get out the shell or skin, in really bad cases packs it with gauze and antibiotics, yes it all sounds gross, we are human, one of my co-workers, kind of a Loni Anderson lookalike, gets these on her head, is very upfront about it, goes to the derm, her daughter likewise.
