Sinus Headache vs. Migraine: How to Tell the Difference

Why do migraines feel like sinus headaches?

Migraine and the sinuses share anatomy and nerve pathways. During a migraine attack, the trigeminal nerve — which supplies sensation to the face, forehead, and sinuses — becomes sensitized. This produces real facial pressure, nasal congestion, watery eyes, and even clear nasal discharge. These symptoms are driven by neurological changes, not by a sinus infection.

Studies consistently show that the vast majority of people who self-diagnose a "sinus headache" actually meet criteria for migraine when formally evaluated. The overlap in symptoms makes the distinction genuinely difficult without a clinical assessment.

What makes a true sinus headache different from a migraine?

A true sinus headache is caused by acute sinusitis — an infection or severe inflammation of the sinus cavities. It typically involves:

• Thick, discolored nasal discharge (yellow or green mucus) rather than clear fluid
• Fever (not always present, but common in bacterial sinusitis)
• Facial tenderness that worsens when you lean forward or press directly over the sinuses
• Symptoms that follow an upper respiratory infection — usually a cold that fails to clear
• Reduced or absent sense of smell (hyposmia or anosmia)
• Pain that does not pulse or throb and is not worsened by routine physical activity

A migraine more often features:

• Throbbing or pulsating pain, typically one-sided
• Nausea or vomiting
• Sensitivity to light (photophobia) and sound (phonophobia)
• Pain that worsens with routine activity like climbing stairs or bending over
• Aura in some people — visual disturbances, tingling, or difficulty speaking before the headache
• Clear nasal congestion and watery eyes that look like allergy or sinus symptoms but lack infection signs
• History of similar attacks that come and go over years

The key distinguishing features are discolored nasal discharge and fever (which point toward true sinusitis) versus nausea, light sensitivity, and throbbing one-sided pain (which point toward migraine) 1Ref 1Rosenfeld RM, Piccirillo JF, Chandrasekhar SS, Brook I, Kumar KA, Kramper M, et al. (2015).Clinical Practice Guideline (Update): Adult Sinusitis.Diagnostic criteria for true sinusitis including discolored discharge, facial tenderness, and fever — distinguishing it from migraine with nasal symptoms.

Can you have both a sinus problem and a migraine?

Yes. People with migraine have higher rates of allergic rhinitis and chronic sinusitis, and sinus inflammation can trigger a migraine attack. In that case, the sinus inflammation may need separate treatment while migraine management addresses the headache component.

This overlap is one reason why seeing a clinician — rather than relying on self-diagnosis — leads to better outcomes. Getting the diagnosis right determines whether the best treatment is a decongestant, an antibiotic, or a migraine-specific medication.

What treatments work for each?

For acute sinusitis: - Most cases (especially viral ones) resolve on their own within 7–10 days with saline rinses, nasal corticosteroid sprays, and symptom management 2Ref 2Lemiengre MB, van Driel ML, Merenstein D, Liira H, Mäkelä M, De Sutter AI (2018).Antibiotics for acute rhinosinusitis in adults.Most sinus infections are viral and resolve without antibiotics; antibiotics should not be routine treatment - Antibiotics are only appropriate for bacterial sinusitis, which has specific diagnostic criteria — most sinus infections are viral and do not respond to antibiotics 2Ref 2Lemiengre MB, van Driel ML, Merenstein D, Liira H, Mäkelä M, De Sutter AI (2018).Antibiotics for acute rhinosinusitis in adults.Most sinus infections are viral and resolve without antibiotics; antibiotics should not be routine treatment - Decongestants can provide short-term relief but should not be used for more than 3 days (rebound congestion is a real risk with sprays)

For migraine: - Acute (abortive) treatments — over-the-counter NSAIDs or acetaminophen for mild attacks; triptans for moderate-to-severe migraine with a clinician's prescription - Preventive treatments are available for people with frequent attacks (typically 4 or more per month); options include beta-blockers, certain antidepressants, anti-epileptics, and newer CGRP-targeting therapies 3Ref 3Charles AC, Digre KB, Goadsby PJ, Robbins MS, Hershey A; American Headache Society (2024).Calcitonin gene-related peptide-targeting therapies are a first-line option for the prevention of migraine: An American Headache Society position statement update.Preventive migraine treatment options for frequent migraine, including newer CGRP-targeting therapies - Identifying and avoiding personal triggers (sleep disruption, dehydration, hormonal changes, certain foods) reduces attack frequency

Over-the-counter "sinus headache" products often contain acetaminophen plus a decongestant. The pain relief in those products comes from the acetaminophen, which may modestly help migraine as well — but the decongestant does nothing for migraine.

When should you see a clinician about your headaches?

It is worth seeing your primary care provider if:

• Headaches are occurring more than once or twice a month
• OTC remedies provide little relief or are needed so often they are becoming a habit (overusing pain medication can cause "rebound" headaches)
• The headache significantly disrupts work, school, or daily life
• You are unsure whether you are treating the right condition

A Gale primary care clinician can review your headache pattern, confirm whether sinus or migraine (or both) is driving your symptoms, and connect you to specialist care if needed.
