Mumps

Another acute viral infection (collect the whole series!), usually confined to the child hood years. Mumps are characterized by inflammation and swelling of the salivary glands and, in teenage and adult males, swelling of one or both testes.
Fortunately, complications are rare, and one bout with mumps confers future immunity. Analgesics are dictated but there is no specific cure known at this time. The only long-term side effect is the social stigma of walking around looking like you're storing nuts for the winter in your cheek pouches. It is not unusual to be given nicknames such as "Squirrel cheeks," "Dizzy," or "Brioche Face" while thus afflicted, and these nicknames may endure for years, causing embarrassment and ridicule that may endanger psychological health during the crucial adolescent years.
Just something to look out for.
