Why Sinus vs Altitude Migraine Confusion Hurts Recovery
If you’ve ever gotten a splitting headache while flying or during allergy season, you’re not alone. I used to blame it on lack of sleep or dehydration—until I realized there’s a difference between sinus headaches and altitude-induced migraines. The confusion is real, and honestly, I wish someone had walked me through the differences years ago. So let’s talk about what sets them apart, why the symptoms overlap so much, and how you can actually figure out which one is hijacking your day.
Understanding the Root Causes
What Triggers a Sinus Headache?
Sinus headaches stem from inflammation or blockage in your sinus cavities—those air-filled spaces behind your forehead, cheeks, and eyes. When they’re clogged up, usually from allergies, infections, or weather changes, the pressure builds up and radiates pain.
- Facial tenderness is common
- Often accompanies nasal congestion
- Pressure worsens when bending forward
Think of it like your sinuses are tiny balloons being slowly overinflated inside your skull. Not fun.
Altitude Migraines: Not Just a “High-Altitude” Thing
Altitude migraines, on the other hand, are triggered by changes in atmospheric pressure—often experienced during flights, hiking in high elevations, or even sudden weather shifts. But here’s the kicker: you don’t have to be scaling Everest to get one.
They’re more common in people who are already prone to migraines. For me, I noticed the pounding would set in like clockwork about 30–60 minutes after takeoff. Turns out, that’s a thing—and it’s not rare.

Key Differences in Symptoms
How They Feel: Side-by-Side
One of the reasons people (including doctors) often confuse these two types is that they share several symptoms—like facial pain, pressure, and sensitivity to light. But if you pay close attention, there are distinct differences.
- Sinus headaches are usually dull and achy, and the pain centers around the cheeks, bridge of the nose, and forehead. You’ll probably feel stuffy or notice nasal discharge.
- Altitude migraines tend to be throbbing, one-sided, and come with nausea, sensitivity to light or sound, and even aura symptoms. No sinus congestion, just a sharp pain that hits differently.
One trick I’ve learned: if I’m blowing my nose constantly and the headache eases a bit, it’s probably sinus-related. If the pain gets worse with movement or bright light? Likely a migraine.

When Altitude Mimics Sinus Issues
This is where things get tricky. Altitude-related pressure changes can also impact your sinuses, especially if you’re already congested. That’s why the two
Misdiagnosis Is More Common Than You Think
One of the reasons I kept treating the wrong type of headache for years was because both sinus and altitude migraines felt similar—and to be honest, over-the-counter meds weren’t helping either way. Turns out, even doctors can confuse the two. In fact, research shows many people who think they have “sinus headaches” actually meet the diagnostic criteria for migraines1.
That’s why proper diagnosis matters. You’re not just chasing relief; you’re targeting the right issue. If your headache comes with watery eyes, nasal congestion, and worsens with allergies, it’s probably sinus-related. But if it comes with nausea, aura, or gets triggered by altitude shifts? You might be dealing with a migraine.

Effective Treatments Tailored to the Cause
For Sinus Headaches
- Decongestants – These shrink swollen nasal passages and relieve sinus pressure.
- Saline rinses – A good old-fashioned neti pot can actually help flush out irritants.
- Antihistamines – Great if allergies are the underlying cause.
- Steam and warm compresses can loosen mucus and provide short-term relief.
If sinus infections are recurring, it might be worth consulting with an ENT or allergist. Persistent issues could hint at structural problems or chronic inflammation that needs deeper evaluation.
Altitude Migraine Relief
Migraines triggered by changes in elevation or pressure often require a different approach:
- Preventive medications like beta-blockers or CGRP inhibitors, especially for frequent flyers or climbers.
- Triptans – These migraine-specific meds work wonders if taken at the onset of symptoms.
- Hydration and electrolyte balance are key—especially in high altitudes.
- Compression eyewear and earplugs can help reduce sensory overload and pressure imbalance.

Natural Ways to Cope with Both
Whether you’re dealing with a sinus or altitude migraine, there are holistic strategies that can complement medical treatments. I’ve personally found yoga, magnesium supplements, and even essential oils to be helpful in reducing the frequency and severity of headaches.
- Try lavender oil for relaxation
- Practice alternate nostril breathing to ease sinus pressure
- Magnesium may reduce the intensity of altitude-induced migraines

Know Your Triggers
Keeping track of what causes your headaches is one of the smartest things you can do. I started logging every episode in a migraine diary app—and patterns popped up fast. Flights, wine, certain weather shifts, and even lack of sleep were major culprits for me.
For sinus headaches, tracking seasonal changes, pollen levels, and allergens can help. For migraines, even changes in altitude or barometric pressure can be tracked with certain apps. Here’s how to set up a simple log: migraine diary guide.
When to See a Specialist
If you’ve tried different treatments and the headaches keep coming back—or getting worse—it might be time to consult a neurologist. They can help rule out underlying neurological issues and personalize a treatment plan. Sinus-related headaches that linger or lead to infections may also need ENT evaluation.
Wondering if it’s time to book that specialist appointment? Here’s when to see a neurologist for migraine.
