What should you know about mumps presentation?

Mumps is a contagious viral infection affecting salivary glands. Swelling may begin on one side and later involve both sides, although the pattern varies. A person can feel unwell before the cheek or jaw becomes visibly enlarged. Fever may accompany the swelling, and the area can feel sore when eating, drinking, or opening the mouth. A swollen gland has many possible causes, so swelling alone does not confirm mumps. Review the condition overview for more context on [Mumps](/conditions/mumps/), and see what [Fever](/symptoms/fever/) or [Swollen Glands](/symptoms/swollen-glands/) can mean in general.

Limit close contact while you arrange advice, especially sharing cups, utensils, towels, or kissing. Rest, drink fluids, and choose soft foods if chewing hurts. Avoid giving medicines intended for someone else; a pharmacist or clinician can help you choose an appropriate option for age, pregnancy, allergies, and other conditions. A [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) can assess the swelling and decide whether testing or additional care is needed. Check your vaccination history and ask whether [MMR Vaccination](/treatments/preventive-care-and-vaccination/mmr-vaccination/) is relevant.

Seek prompt medical advice for new jaw or cheek swelling with fever, particularly after contact with someone who has mumps. Get urgent help for severe headache, stiff neck, confusion, repeated vomiting, breathing difficulty, inability to swallow fluids, severe abdominal pain, or sudden testicular pain or swelling. Call ahead before attending a clinic so staff can reduce exposure to other patients.

Could this swelling be mumps or another salivary-gland problem? How long should I avoid close contact? Do I need testing, and which symptoms should trigger urgent review? Should my household check their MMR vaccination status?
