Ideally, he should be examined by your veterinarian. Never medicate a pet without the advice of your veterinarian. Inappropriate antibiotic use can lead to resistant bacteria and may complicate any underlying conditions, possibly delaying diagnosis. The lump may have been a cyst or abscess that ruptured. If it is bleeding, painful or if the discharge doesn't stop, then have Rocket seen at the nearest veterinary ER tonight. If Rocket is not bleeding, painful and behaving normally, clean the area with a warm washcloth or pet wipe and have him examined tomorrow.
