Inflammation of the pancreas(Acute pancreatitis) and inflammation of the ovaries(called oophoritis) can occur and one in 4 men who catch mumps after puberty develop inflammation of the testicles(orchitis), which is painful and , though it does not make a man sterile, it is a major cause of reduced male fertility(sub-fertility).Complications with mumps may set in about a week after symptoms begin. In some cases there may be signs of irritation of the brain membrane(meningitis).Symptoms include headache, neck stiffness, vomiting and dislike of light. Hearing loss may follow mumps but it's usually one-sided and temporary.
