How common is facial swelling in sinusitis?

Sinusitis involves inflammation of the lining of the sinuses. Nasal blockage, discharge, reduced smell, facial pressure and tooth discomfort can occur alongside swelling. The location may suggest which sinus is irritated, but the pattern is not enough to confirm a cause without an assessment. Facial swelling can also result from dental, skin, allergic or eye conditions.

Rest, drink fluids and use simple pain relief only if it is suitable for you. Saline nasal rinsing may help clear mucus for some people; use clean water prepared according to the product instructions. Arrange a clinical review if symptoms are severe, persist, recur, or swelling is new. Tell the clinician about recent dental problems, injury, allergies and medicines you use.

Urgent assessment is needed for swelling or redness around an eye, vision changes, double vision, severe headache, neck stiffness, confusion or pain when moving an eye. Seek help promptly if facial swelling is rapidly increasing or you are very unwell. These warning signs can point to problems beyond uncomplicated sinus inflammation.

Ask whether the symptoms fit sinusitis or another facial condition, whether the eye or teeth need checking, and which symptoms should trigger an earlier review. Ask how to use any recommended nasal treatment safely.
