What should you know about cluster headaches caused by sinus?

Sinus inflammation may cause blocked or runny nose, facial pressure, reduced smell, and discomfort that changes with congestion. Cluster headache can also cause one-sided nasal blockage or discharge, but it is classically linked with intense pain around one eye or temple, tearing, eyelid changes, and restlessness. The shared nose symptoms can make self-diagnosis unreliable. A clinician will consider timing, side, pain quality, recent infection, allergies, and examination findings rather than treating every facial pressure episode as sinus disease.

Keep a record of nasal symptoms, facial pressure, eye changes, headache features, fever, and possible allergy or infection triggers. Arrange a GP consultation when symptoms persist, recur in a distinctive pattern, or are not improving as expected. Avoid using decongestant sprays or leftover antibiotics beyond professional advice. More background is available on [Facial Pain and Pressure](/symptoms/facial-pain-and-pressure/) and [Headache](/symptoms/headache/).

Get urgent medical help for swelling around the eye, vision changes, severe sudden headache, confusion, weakness, stiff neck with fever, or a rapidly worsening illness. Facial swelling with difficulty breathing or swallowing is an emergency. These features need prompt assessment because serious eye, neurological, or spreading infectious problems can resemble ordinary sinus discomfort.

Ask whether your pattern better fits sinus inflammation, cluster headache, or another headache disorder; whether an examination is needed; and which treatments are appropriate for the suspected cause. Ask how to recognise a change that requires urgent review.
