Most headaches that feel like sinus infections are actually migraines. Roughly 80% of people who visit a doctor for what they believe is a sinus headache turn out to meet the diagnostic criteria for migraine. That matters because treating a migraine as a sinus problem means taking the wrong medications, getting no relief, and sometimes suffering through years of unnecessary antibiotics and decongestants. The good news: once you treat the right condition, the pressure, congestion, and facial pain can resolve quickly.
Why It Feels Like a Sinus Problem
Migraine activates the trigeminal nerve, which runs through your forehead, cheeks, and jaw. When this nerve fires during a migraine attack, it triggers an automatic response from your parasympathetic nervous system. That response produces real, measurable sinus symptoms: nasal congestion, runny nose, watery eyes, and pressure around your cheekbones and forehead. These aren’t imaginary. Your sinuses are genuinely reacting, but they’re reacting to nerve signals from the migraine, not to an infection.
One study of 130 patients who had been diagnosed and treated for sinusitis found that 81.5% of them actually had migraine. Many had been misdiagnosed for years. The distinguishing clues are subtle but important. True sinus infections typically come with thick, discolored nasal discharge, fever, and reduced sense of smell. Migraines with sinus symptoms tend to involve sensitivity to light or sound, nausea, throbbing pain that worsens with movement, and attacks that last between 4 and 72 hours before resolving. If your “sinus headaches” come and go in episodes, especially around weather changes or your menstrual cycle, migraine is the far more likely explanation.
Over-the-Counter Pain Relief
For mild to moderate attacks, anti-inflammatory pain relievers are the first step. Ibuprofen and naproxen both reduce the inflammation involved in migraine and can ease sinus pressure at the same time. Naproxen lasts longer, which makes it a practical choice for attacks that drag on. A typical starting dose for adults is 550 mg, followed by another dose 12 hours later if needed. Combination products that pair a pain reliever with caffeine can also be effective, since caffeine narrows dilated blood vessels and helps your body absorb the medication faster.
The critical rule with any over-the-counter pain reliever is frequency. Using these medications more than two or three days per week can cause rebound headaches, where the pain returns as the drug wears off and gradually becomes more frequent. If you find yourself reaching for pain relievers that often, it’s a signal to explore preventive options.
Prescription Treatments for Acute Attacks
When over-the-counter options aren’t enough, prescription migraine medications called triptans are the standard treatment. These work by targeting serotonin receptors in the brain, calming the trigeminal nerve activity that produces both the head pain and the sinus symptoms. In a randomized controlled trial of patients who described their headaches as “sinus headaches,” those treated with sumatriptan (a triptan) were significantly more likely to be free from sinus pain: 63% at two hours compared to 49% on placebo, and 77% at four hours compared to 55%. The fact that a migraine-specific drug resolves sinus pain reinforces that the underlying problem is migraine, not sinusitis.
Triptans come in tablets, nasal sprays, and injections. Nasal sprays can be especially appealing if nausea makes swallowing a pill difficult, and some people feel poetic justice in treating sinus-area pain with a nasal spray. Your doctor can help match the formulation to how your attacks typically unfold.
Preventing Frequent Attacks
If you’re getting four or more migraine days per month, preventive treatment can reduce how often attacks happen and how severe they are. As of 2024, the American Headache Society considers newer medications that block a protein called CGRP (a key player in migraine pain signaling) to be a first-line preventive option. That’s a significant shift. Previously, patients had to try and fail older preventive medications before qualifying. Now these targeted therapies can be prescribed without that gatekeeping step. They’re available as monthly or quarterly injections you give yourself at home, and they’re approved for both episodic migraine (4 to 14 migraine days per month) and chronic migraine (15 or more headache days per month).
Older preventive medications still work well for many people. These include certain blood pressure medications, antidepressants, and anti-seizure drugs that happen to reduce migraine frequency as a side effect. The best choice depends on your other health conditions and what side effects you’re willing to tolerate.
Supplements That Reduce Migraine Frequency
Two supplements have enough clinical evidence behind them to be worth trying. Riboflavin (vitamin B2) at 400 mg daily has been shown to reduce migraine frequency and intensity. UK headache guidelines specifically recommend it. Magnesium, taken at around 400 mg daily, also has evidence supporting its role in prevention, particularly for people whose migraines are triggered by menstruation or weather changes. Both take about two to three months of consistent daily use before you’ll notice a difference, so patience is required. They’re generally well tolerated, though magnesium can cause loose stools at higher doses.
Weather and Barometric Pressure Triggers
If your “sinus headaches” reliably show up before storms or during weather shifts, barometric pressure is likely your trigger. Research has shown that migraine attacks most frequently develop when atmospheric pressure drops to 6 to 10 points below standard levels, which typically happens just before a cyclone or storm system moves in. The mechanism involves changes in blood vessel dilation inside the brain: falling pressure causes blood vessels to expand, which activates the trigeminal nerve and sets the migraine cascade in motion.
You can’t control the weather, but you can plan around it. Smartphone apps that track barometric pressure let you anticipate vulnerable windows and take a pain reliever early, before the attack fully develops. Treating a migraine in the first 20 to 30 minutes consistently produces better outcomes than waiting until the pain peaks.
Nerve Stimulation Devices
For people who want to avoid medications or need something additional, FDA-cleared wearable devices offer a drug-free option. The Cefaly device, worn on the forehead like a headband, sends mild electrical pulses to branches of the trigeminal nerve. It’s cleared for both treating active attacks and preventing future ones. In a controlled trial, patients using the device during an attack experienced a 59% decrease in pain after 60 minutes, compared to 30% in the group using a sham device. A second device, HeadaTerm, showed even more dramatic results in an emergency department study: patients experienced an average 65-point pain reduction on a 100-point scale after just 20 minutes of stimulation, compared to a 9-point reduction with a placebo device.
These devices won’t replace medication for everyone, but they’re useful as an add-on treatment or for people who can’t tolerate or prefer to limit drug use.
What to Stop Doing
If your headaches are migraines rather than true sinus infections, certain common “sinus headache” remedies may be wasting your time or making things worse. Decongestant nasal sprays like oxymetazoline provide temporary relief by shrinking nasal tissue, but they don’t address the migraine itself, and using them for more than three consecutive days causes rebound congestion. Repeated courses of antibiotics for headaches that aren’t caused by bacterial infection contribute nothing except side effects and antibiotic resistance. Steam inhalation and saline rinses feel soothing and won’t cause harm, but they’re treating a symptom, not the source.
The single most effective step is getting the diagnosis right. If you’ve been treated for sinus problems repeatedly without lasting improvement, especially if your headaches involve light sensitivity, nausea, or throbbing pain, bring up migraine with your doctor. A correct diagnosis opens the door to treatments that actually work.
Headache Symptoms That Need Urgent Attention
Most sinus-type migraines, while miserable, aren’t dangerous. But certain headache features signal something more serious. Seek immediate medical care for a headache that reaches maximum intensity within seconds (a “thunderclap” headache), any headache accompanied by fever and a stiff neck, new headaches with neurological symptoms like vision loss, weakness on one side of the body, confusion, or seizures, and headaches that are triggered or dramatically worsened by coughing, sneezing, or physical exertion. A headache pattern that has fundamentally changed from what you’re used to, or one that progressively worsens over days to weeks, also warrants prompt evaluation.
