A sinus headache feels like deep, constant pressure across your forehead, cheekbones, or the bridge of your nose. The pain is often described as achy and tender rather than sharp or throbbing, and it typically gets worse when you bend forward or lie down. But here’s something most people don’t expect: studies show that about 90% of people who believe they have a sinus headache are actually experiencing a migraine.
Where the Pain Shows Up
The pain maps closely to where your sinuses sit behind your face. You’ll feel it most in three areas: across your forehead (above your eyebrows), in your cheekbones on either side of your nose, and sometimes deep behind and between your eyes. The sensation is more like a heavy, full ache than a stabbing pain. Your face may feel swollen or puffy even when it doesn’t look that way from the outside.
Pressing on the affected areas typically makes the pain worse. Doctors sometimes tap gently on the forehead or cheekbones to check for tenderness, and if you wince, that’s a telling sign. The pain can also radiate to your upper teeth or jaw, which sometimes sends people to a dentist before they realize the problem is in their sinuses.
Why It Feels That Way
Your sinuses are hollow, air-filled pockets behind your facial bones. When you get a cold, allergies, or an infection, the tissue lining those pockets swells and starts producing extra mucus. That swelling traps mucus so it can’t drain, and bacteria or viruses settle into the stagnant fluid. The result is inflamed, fluid-filled cavities pressing outward against bone and sensitive tissue. That trapped pressure is what creates the deep, achy sensation across your face.
Bending over or lying flat makes the pain spike because those positions shift fluid inside the blocked sinuses, increasing the pressure against already-irritated tissue. Many people notice the headache is worst first thing in the morning, after hours of lying down have allowed mucus to pool.
Other Symptoms That Come With It
A true sinus headache almost never shows up alone. It comes packaged with signs of a sinus infection or significant inflammation. You should expect some combination of these:
- Thick, discolored nasal discharge. Yellow or greenish mucus from your nose, or dripping down the back of your throat (postnasal drip), is one of the most reliable indicators.
- Nasal congestion. Breathing through your nose feels partially or fully blocked.
- Reduced sense of smell. Swollen sinus tissue dulls your ability to smell or taste.
- Cough. Postnasal drip irritates the throat and triggers coughing, often worse at night.
If you have facial pressure but none of these additional symptoms, the pain is probably not coming from your sinuses.
Why It’s Probably a Migraine
This is the single most important thing to know about sinus headaches: the vast majority of self-diagnosed cases turn out to be migraines. The confusion happens because migraines frequently cause pain in the exact same facial areas and can even trigger nasal congestion and a runny nose through nerve pathways that activate during an attack. So you feel pressure across your cheekbones, your nose gets stuffy, and you reasonably conclude it’s your sinuses.
A few questions help sort it out. Do you feel nauseous during the headache? Does light or noise bother you more than usual? Does the pain get noticeably worse with physical activity or sudden movement? People with genuine sinus headaches rarely answer yes to those. People with migraines almost always do. If your “sinus headaches” keep coming back, especially if they tend to hit on one side of your face or arrive with visual disturbances, you’re likely dealing with migraines and could benefit from migraine-specific treatment.
How Long Sinus Headaches Last
The timeline depends on what’s causing the sinus inflammation. Acute sinusitis, the most common type, typically resolves within 10 days. The headache follows the same arc: it builds as congestion worsens, peaks when the sinuses are most blocked, and fades as mucus begins draining again. If you’re recovering from a cold, the worst of the facial pain usually hits a few days in and improves steadily over the following week.
Chronic sinusitis is a different situation. Symptoms that persist for 12 weeks or longer fall into this category, and the headache can become a low-grade daily companion rather than an intense but temporary problem. Chronic cases often involve structural issues like nasal polyps or a deviated septum that keep the sinuses from draining properly, and they typically need more targeted treatment than over-the-counter decongestants can provide.
Sinus Headache vs. Other Headaches
A tension headache feels like a band tightening around your entire head. It’s usually mild to moderate, affects both sides equally, and doesn’t come with nasal symptoms. A sinus headache is more localized to specific facial zones and is always accompanied by congestion or discharge.
Migraines tend to be more intense, often pulsing or throbbing, and frequently favor one side of the head. Nausea, sensitivity to light and sound, and pain that worsens with movement are hallmarks of migraine. The tricky overlap is that migraines can produce facial pressure and nasal stuffiness, which is why misdiagnosis is so common. The key differentiator is what else is happening: thick, discolored mucus and a recent cold or respiratory infection point toward sinuses. Nausea, light sensitivity, and recurring episodes point toward migraine.
Signs of a Serious Problem
Most sinus headaches are uncomfortable but not dangerous. However, a small number of sinus infections spread beyond the sinuses into surrounding tissue. Get prompt medical attention if your sinus symptoms come with any of the following: fever, swelling or redness around your eyes, forehead swelling, confusion, double vision or other visual changes, or a stiff neck. These can indicate the infection is affecting the eye socket or, rarely, the brain, and they require immediate evaluation.
