Most self‑diagnosed sinus headaches are migraines. The facial pressure, the congestion, the tearing eye and the weather sensitivity are all migraine features, and treating them with antibiotics and decongestants for years is one of the most common wrong turns in headache medicine.

Getting here from St. Charles

St. Charles is the closest large community to our Natural Bridge Road office — roughly 7.4 miles, about 13 minutes across the Blanchette Bridge on I‑70 eastbound. Parking is surface level and the building is at ground floor, which is worth mentioning for anyone arriving during an attack with light sensitivity.

Is a sinus headache usually a migraine?

When researchers took patients who were convinced they had sinus headaches and applied formal diagnostic criteria, the great majority met criteria for migraine or probable migraine instead. True sinusitis headache requires purulent discharge, fever, and an actual infection — and it resolves when the infection does.

The confusion is understandable, because migraine genuinely produces sinus symptoms. The trigeminal nerve supplies both the sinuses and the dura, and activation of the trigeminovascular system produces facial pressure, nasal congestion, rhinorrhea, tearing and eyelid changes in a substantial share of migraine attacks.

So the patient is not imagining the sinus symptoms. They are real. They are just not caused by an infection. Sinus headache or migraine works through the distinction properly.

How can you tell a sinus headache from a migraine?

A handful of features do most of the work:

Nausea, or sensitivity to light and sound, which are migraine features and not sinusitis features
A throbbing or pulsing quality rather than a constant pressure
Worsening with routine physical activity — climbing stairs, bending forward
Attacks lasting four to seventy‑two hours and then resolving completely, rather than a persistent multi‑week course
A history of the same headaches going back years, which infection does not do
Purulent nasal discharge and fever, which point genuinely toward sinusitis

If someone has had these headaches for a decade, has never had a fever with them, and feels nauseated during attacks, the diagnosis is not in much doubt.

Why does it matter whether it is sinus headache or migraine?

Because the treatments do not overlap at all. Repeated antibiotic courses for a condition that is not infectious carry real cost — resistance, gut effects, and the years lost.

Decongestants used frequently can drive rebound congestion and, if combined with over‑the‑counter analgesics several days a week, can produce medication overuse headache layered on top of the original problem. That is a common and entirely avoidable second diagnosis.

Meanwhile the effective treatments for migraine — the acute ones and the preventive ones — go untried. Acute treatment and triptans and preventive treatment options cover what those actually are.

Can a sinus CT scan show what is causing my headache?

CT of the sinuses in a patient with facial pressure frequently shows mucosal thickening. That finding is present in a large share of asymptomatic adults and does not establish that the sinuses are causing the headache.

This is the same problem that plagues spine imaging: an incidental finding gets promoted to a diagnosis because it is the only abnormality visible. A normal sinus CT during an attack is far more informative than an abnormal one between attacks.

Do I need a scan covers when imaging genuinely changes management in headache and when it mostly generates incidental findings.

Where our practice fits

This is an interventional pain practice with a headache focus, not a general neurology clinic, and the distinction is worth being clear about. What we do well is diagnosis, procedural treatment of the headache types that respond to it, and coordination with neurology where medication management is the right route.

For migraine specifically that includes occipital nerve blocks and sphenopalatine ganglion blocks, both of which have a defined role and neither of which is a substitute for a preventive strategy in someone having frequent attacks.

Which doctor for headaches sets out who does what, and it is an honest map rather than a pitch.

What does a first visit with a headache doctor settle?

Four things, and they are worth naming because a headache appointment that does not produce them has not finished. What the headache actually is, using the formal criteria rather than a label. What has been excluded and on what basis. A specific acute plan for the next attack, including what to take, at what dose, and how early. And a preventive plan if the frequency warrants one.

The acute plan is the part most often left vague. Timing matters more than dose in acute migraine treatment — medication taken early in an attack works substantially better than the same medication taken two hours in, and most patients have been told to wait and see whether it gets bad. That single change improves results for a good number of people before anything is added.

What happens at a headache clinic describes the visit, and acute treatment and triptans covers the timing question in detail.

Frequently asked questions from St. Charles patients

I get relief from decongestants. Doesn’t that prove it is sinus?

No. Decongestants have vasoconstrictive effects and many combination products contain caffeine or an analgesic, both of which help migraine. Responding to a sinus medication is weak evidence for a sinus cause and it is one of the more common reasons people stay with the wrong diagnosis.

My headaches get worse when the weather changes. Isn’t that sinus?

Barometric sensitivity is a well‑recognized migraine trigger and it is often taken as evidence of sinus involvement. It points the other way. Weather and barometric headache covers what is known about the mechanism.

Do I need a referral to be seen?

No. You can book directly. If your insurance requires a referral for specialist visits we will tell you before the appointment rather than after.

What should I bring to the first visit?

A headache diary if you have one, even a rough one. Dates, duration, what you took and whether it worked are the most useful data in headache medicine and they are usually missing. How to keep a headache diary covers what to record and what to bring covers the rest.

Why do I feel sinus pressure and congestion during a migraine?

Because migraine runs through the trigeminal nerve, which supplies both the sinuses and the lining around the brain. When that system fires, it produces real facial pressure, nasal congestion, a runny nose, tearing and eyelid changes. The symptoms are not imagined. They are just not caused by an infection, which is why antibiotics and decongestants keep missing the actual problem.

How do you get rid of a sinus migraine?

Treat it as the migraine it is. That means a specific acute plan taken early in the attack, because timing matters more than dose, and a preventive plan if the attacks are frequent. It also means stopping the frequent decongestant and over-the-counter painkiller routine, which can add medication overuse headache on top of the original problem. Nerve blocks have a defined role for some patients.

Who is the best doctor to see for headaches?

The one who settles what the headache actually is. Our practice is an interventional pain practice with a headache focus, not a general neurology clinic. We handle diagnosis with formal criteria, procedural treatment such as occipital nerve blocks and sphenopalatine ganglion blocks for the headache types that respond to them, and coordination with neurology when medication management is the right route.
