Before I describe it, I would like to address all the WebMD idiot know-it-alls that have replied with their interperetations and their advice- you wheren't there, you know nothing. The DOCTOR who saw the wound afterward made the diagnosis that it was a Sebacous Cyst. Also, before attempting a home lancing they got with the doctor for his advice. Rather than wait a day while the patient was in pain from the pressure, they lanced it at home as the doctor suggested.
The cyst developed for years completely un-noticed, deep under the skin (the reservoir was described as as deep and big around as your little finger). A bump started to form over the course of a few days before the lancing, and at night the patient hit it with his foot in bed and woke up from the pain. They called the doctor and his suggestion was a home lancing and the patient could come in the next day for a full cleaning. His grandmother with prior medical experience did it at home and the next day he went to the doctor to get it cleaned. His brother, mother, and friend YouTube user WNunzioVaiana (filming) are in the background.
