What could this nasty discharge be a sign of (see pic)?

HI LOOK I THINK YOU SHOULD GO TO THE HOSPITAL IT DOES NOT MATTER IF U DONT HAVE INSURANCE...THEY WILL STILL ATTEND YOU....YOU CAN MAKE PAYMENT ARRANGEMENTS. YOU SHOULD WAIT LONG ITS BETTER IF YOU GET CHECK RIGHT NOW BEFORE ITS TOO LATE MAYBE ITS NOT SOMETHING REALLY BAD BUT FOR YOUR OWN GOOD.
