Irritation between the nose and throat

The nose and throat form one connected airway, so swelling or mucus in one area can be felt in the other. Allergic rhinitis may cause sneezing, itching, congestion and clear drainage. A common cold can add soreness, tiredness and thicker mucus. Dust mites, pollen, mould or animal dander may repeatedly irritate the lining. Food allergy is a separate possibility when symptoms follow a particular food and may include hives, swelling, vomiting or breathing symptoms. Dry air, mouth breathing and smoke can also aggravate the tissues.

Drink water and avoid smoke, vaping and heavily scented products. Saline spray or a gentle nasal rinse may loosen mucus; follow product instructions and use safe water for rinsing. Wash hands and rest if cold symptoms are present. If symptoms follow dust or pollen exposure, reduce exposure where practical and keep bedroom fabrics clean. Allergy medication may help some people, but a pharmacist or clinician should check the choice if you are pregnant, have other conditions or take regular medicines. Do not deliberately re-test a suspected food trigger.

Seek emergency help for trouble breathing, sudden swelling of the tongue or throat, faintness or widespread hives after eating. Arrange prompt care for severe dehydration, marked illness, persistent one-sided facial pain or symptoms that are rapidly worsening. Make an appointment if irritation keeps returning, affects sleep, causes difficulty swallowing, or does not improve after a cold has passed. A clinician can examine the nose and throat and review possible environmental or food triggers.

Ask whether your pattern fits allergy, a cold, post-nasal drainage or another cause. Tell the clinician what you were exposed to, whether symptoms follow meals, and whether you have itching, rash, fever, facial pain or breathing changes. Ask which nasal or allergy treatment is suitable and how to use it safely.
