What should you know about mumps swelling behind ear?

Mumps is a viral infection that commonly affects the salivary glands near the jaw. Nearby lymph glands can also become enlarged as the immune system responds. Swelling may begin on one side and later affect both sides, with pain when chewing or swallowing. A swollen area behind the ear can also have other causes, including a local infection, so the location alone cannot confirm mumps.

Stay home from school, work, or group activities while you seek advice, especially if fever or gland swelling is present. Avoid sharing cups, utensils, towels, and close face-to-face contact. Rest, drink fluids, and choose soft foods if chewing hurts. Use only pain or fever medicine suitable for you and follow the label; never give aspirin to a child unless a clinician says to. A [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) can help distinguish mumps from another cause and advise on testing or isolation.

Seek prompt medical advice for new swelling with fever, worsening pain, or difficulty eating and drinking. Get urgent help for trouble breathing or swallowing, severe headache, stiff neck, confusion, repeated vomiting, marked drowsiness, or severe pain in the testicle or lower abdomen. Call ahead before attending a clinic so staff can reduce exposure to other people.

Could this be mumps or another gland infection? How long should I avoid close contact? Do I need an examination or test, and which symptoms should prompt urgent review?
