They are infected glands
. You can get them in and around crotch, buttucks, arm pits
, etc. Most people get them becouse when you shave, it allows germs to get into the glands. They may go away for a short time but, the only way to trully get relief is to have a Dr do surgery to remove each infected gland. This may need to be reppeated. To prevent them from spreading, soap well during shaving, use only new razors, and never shave during an outbreak of even one!
