HELP!

okay, so last week i had an ingrown hair and it was impossible to get out but it hurt sooo bad so i tweezed it out, & it wasnt red or anything anymore. but last night i noticed i had a bump the same place the hair was (i havent shaved because im scared to lol) , but this morning it looked like a pimple i squeezed it and puss came out then about 20 minutes later it got really dark as in this pic. someone help me?
