I heard mumps is making a return - has he been vaccinated for that? Did they even suggest that? They way you described the HUGE bumps on the neck. You could have huge ones on both sides or just one side. As a kid I had mumps but only one the one side. Oh if he was septic you'd KNOW it!! I knew a young woman whose infection went septic - HIGH fever, she passed out, she was REALLY sick.
