When “sinus pressure” is real—and when it’s actually migraine
Sinus headache pain comes from inflamed, blocked sinuses, but many “sinus headaches” are migraines. Get clear next steps, labs, and no-referral care.
A “sinus headache” is head or face pain that’s driven by swollen, irritated sinus passages, which traps mucus and creates pressure. The tricky part is that many headaches people call sinus headaches are actually migraines, so the right treatment depends on the pattern of your symptoms. If you feel pressure in your cheeks, forehead, or behind your eyes—especially with a stuffy nose or thick drainage—sinus inflammation may be the culprit. This guide walks you through the signs that point toward sinus trouble, the common causes (from colds to allergies), how clinicians tell sinus pain from migraine, and what helps at home versus what needs prescription care. If you want help sorting your symptoms quickly, PocketMD can guide you through the key questions, and VitalsVault labs can support a broader workup when fatigue, frequent infections, or allergy-like symptoms keep repeating.
Symptoms that fit a sinus headache
Facial pressure that worsens when bending
Sinus-related pain often feels like a deep pressure in your forehead, cheeks, or between your eyes, and it can spike when you bend forward or lie down. That position change shifts pressure in swollen sinus spaces, which is why it can feel like your face is “too full.” If the pain is strongly tied to congestion and posture, sinus inflammation moves higher on the list.
Stuffy nose with thick drainage
When your sinus openings are swollen, mucus can’t drain well, so you may feel blocked on one or both sides. Thick yellow or green drainage can happen with viral infections and with bacterial infections, so color alone does not prove you need antibiotics. What matters more is whether symptoms are steadily improving or getting worse after a brief improvement.
Pain in upper teeth or jaw
Your upper back teeth sit close to the maxillary sinuses, so swelling there can refer pain into your teeth and gums. It can feel like a dental problem even when your teeth are fine. If the tooth pain is paired with congestion and facial pressure, it often points back to your sinuses rather than a single tooth.
Reduced smell and postnasal drip
Swelling in your nose can dull your sense of smell, and mucus may drip down the back of your throat, which can trigger coughing or a scratchy throat. This is annoying, but it is also a clue that the problem is happening in your nasal passages, not just “in your head.” If you notice a bad taste or constant throat clearing, postnasal drip is often the reason.
Red flags that need urgent care
Get urgent help if you have a severe headache with a stiff neck, confusion, fainting, new weakness, or the “worst headache of your life,” because those are not typical sinus symptoms. Also take eye symptoms seriously: swelling around one eye, double vision, trouble moving your eye, or vision changes can signal a complication that needs same-day evaluation. High fever with worsening facial pain after a week of illness is another reason to be seen promptly.
Lab testing
If headaches keep recurring with fatigue or frequent “colds,” consider baseline labs starting from $99 panel with 100+ tests, one visit to look for inflammation, anemia, and immune or allergy clues.

Causes and risk factors
Viral cold causing sinus swelling
Most sinus pressure starts with a regular viral cold that inflames the lining of your nose and sinus openings. When those tiny drainage pathways narrow, mucus backs up and pressure builds, which can feel like a heavy ache in your face. The good news is that viral sinus symptoms usually improve over 7–10 days, even if the first few days feel intense.
Allergies that keep inflammation simmering
Seasonal or indoor allergies can keep your nasal lining irritated, which makes you more likely to feel pressure and get “stuck” congestion. You might notice itching, sneezing, watery eyes, or symptoms that flare in specific places like your bedroom. When allergies are the driver, treating the inflammation consistently often helps more than chasing pain alone.
Acute bacterial sinus infection
A bacterial sinus infection is more likely when symptoms last beyond about 10 days without improvement, or when you get better and then suddenly get worse again. The pain can become more localized to one side, and the pressure may feel sharper rather than just “full.” This is the scenario where a clinician may consider antibiotics, especially if you also have fever or significant facial tenderness.
Nasal polyps or a deviated septum
Structural issues can narrow the pathways that let your sinuses drain, which makes pressure and infections more likely. Polyps are soft growths from chronic inflammation, and a deviated septum is a shifted wall inside your nose that can block airflow. If you feel chronically congested on one side or you keep getting the same-sided pressure, it is worth asking whether anatomy is part of the story.
Migraine mistaken for “sinus” pain
Migraine can cause forehead and face pressure, and it can even cause a runny nose or watery eyes, which is why it fools so many people. If your headache comes with nausea, light sensitivity, sound sensitivity, or a throbbing quality, migraine becomes more likely than sinus disease. This matters because decongestants and antibiotics won’t fix migraine, but migraine-specific treatment often can.
How it’s diagnosed
Your symptom timeline tells the truth
Clinicians lean heavily on the pattern: how long symptoms have lasted, whether they are improving, and whether you had a “double-worsening” after initial recovery. That timeline helps separate a viral illness from a bacterial infection and from migraine. Bringing a simple day-by-day note of pain, congestion, fever, and meds you tried can speed up the visit.
Nasal and throat exam (and sometimes a scope)
A basic exam looks for swollen nasal tissue, pus-like drainage, and tenderness over the sinuses, along with signs of allergies like pale, boggy lining. In some clinics, a small camera exam of your nose (nasal endoscopy) can show where drainage is coming from and whether polyps are present. Seeing the inside can prevent guesswork when symptoms keep recurring.
When imaging helps—and when it doesn’t
A CT scan of your sinuses is usually reserved for chronic symptoms, complications, or planning for surgery, because many people show “sinus changes” on scans even when the pain is from migraine. If you have severe one-sided symptoms, eye involvement, or repeated infections despite good treatment, imaging can clarify whether there is blockage or an anatomic issue. For routine short-lived symptoms, imaging often adds cost without changing what you do.
Labs only when the story suggests more
Most straightforward sinus headaches do not need blood tests, but labs can be useful if you are frequently ill, unusually tired, or dealing with symptoms that don’t fit a simple cold. A clinician might look for anemia, inflammation markers, or immune and allergy clues depending on your history. If you are building a broader picture, VitalsVault lab options can be a convenient starting point to bring objective data into the conversation.
Treatment options that actually help
Saline rinses to restore drainage
A saline rinse or spray helps thin mucus and physically wash irritants out of your nose, which can reduce pressure over a few days. Use distilled, sterile, or previously boiled and cooled water for any rinse device, because tap water is not safe for nasal irrigation. If you do this once or twice daily during a flare, many people notice less “stuck” congestion.
Nasal steroid spray for inflammation
A daily nasal steroid spray reduces swelling in the nasal lining, which opens drainage pathways and helps prevent rebound congestion. It is not an instant decongestant, so it works best when you use it consistently for several days to weeks. Good technique matters: aim slightly outward toward your ear, not straight up the middle of your nose.
Pain relief and smart decongestant use
Anti-inflammatory pain relievers can take the edge off facial pain, especially when swelling is part of the problem. Decongestant sprays can help briefly, but if you use them for more than about three days you can trigger rebound congestion that feels worse than the original problem. Oral decongestants can raise blood pressure or make you jittery, so they are not a great fit for everyone.
Antibiotics only in the right scenario
Antibiotics help when bacteria are likely, which is usually when symptoms persist beyond about 10 days without improvement, or when you worsen again after starting to recover. Taking antibiotics too early does not speed up a viral illness, and it can cause side effects like diarrhea or yeast infections. If a clinician recommends antibiotics, ask what signs made bacterial infection the most likely explanation in your case.
If it’s migraine, treat it like migraine
When your “sinus headache” comes with nausea, light sensitivity, or a pounding quality, migraine treatment can be the turning point. That might mean migraine-specific medications, avoiding personal triggers, and using the right rescue plan early in the attack. Getting the label right is not semantics—it changes what actually works.
Living with recurring sinus pressure
Track patterns without obsessing
A short log can help you notice whether flares follow colds, allergy seasons, dusty rooms, or weather shifts. Keep it simple: when the pressure starts, what your nose is doing, and what helped within two hours. The goal is not perfection—it is spotting the repeatable pattern that guides prevention.
Hydration, humidity, and sleep positioning
Thicker mucus drains poorly, so staying hydrated and using a humidifier in dry months can make symptoms feel less “cement-like.” Sleeping with your head slightly elevated can reduce nighttime congestion and morning pressure. If humidity worsens your symptoms, that can be a clue that mold or dust mites are part of the trigger.
Know when to ask about ENT evaluation
If you have symptoms most days for more than 12 weeks, or you keep getting infections that bounce back, it may be time to talk about chronic sinus inflammation. An ear, nose, and throat specialist can check for polyps, structural blockage, or ongoing inflammation that needs a different plan. You deserve an explanation that matches how often this is disrupting your life.
Protect your gut and routine during treatment
If you do need antibiotics, taking them exactly as directed and watching for side effects helps you avoid a second problem while fixing the first. If diarrhea is severe, bloody, or persistent, contact your clinician rather than trying to push through. For many people, the bigger win is building a prevention routine so antibiotics are the exception, not the pattern.
Prevention and reducing flare-ups
Treat allergies before they snowball
If your sinus headaches cluster around pollen season or indoor triggers, consistent allergy control can prevent the swelling that starts the whole cycle. That might include daily nasal steroid spray during your season and targeted antihistamines when symptoms flare. When you control inflammation early, you are less likely to end up with pressure and pain later.
Use saline during colds, not just after
Starting saline rinses early in a cold can keep mucus moving and reduce the chance that your sinuses get blocked. Think of it as maintenance for drainage rather than a last-ditch fix. If you wait until day five when everything is stuck, it can still help, but it often takes longer to feel relief.
Reduce irritants in your air
Smoke, strong fragrances, and very dry air can inflame your nasal lining even when you are not “sick.” If you notice pressure after certain exposures, improving ventilation and avoiding the trigger can be more effective than adding another medication. Your nose is a filter, and filters work better when they are not constantly irritated.
Get the diagnosis right for recurring headaches
If you keep treating “sinus headaches” and nothing changes, it is worth revisiting whether migraine or another headache type fits better. The right diagnosis prevents months of ineffective decongestants and unnecessary antibiotics. A clear plan—what to do on day one, day three, and day ten—can save you a lot of pain.
Frequently Asked Questions
How can you tell a sinus headache from a migraine?
Sinus-related pain usually travels with congestion, thick drainage, and pressure that changes when you bend forward. Migraine is more likely if you have nausea, light or sound sensitivity, or a throbbing headache that disables you even when your nose is not very blocked. If you keep getting “sinus headaches” without much nasal symptom change, ask specifically about migraine.
Do green or yellow mucus and facial pressure mean you need antibiotics?
Not necessarily, because viral infections can also cause thick, colored mucus. Antibiotics are more likely to help when symptoms last beyond about 10 days without improvement, or when you improve and then get worse again. A clinician will also consider fever, severity, and whether pain is localized to one side.
What is the fastest way to relieve sinus pressure at home?
For many people, a saline rinse plus a consistent anti-inflammatory nasal spray provides the most meaningful relief because it improves drainage rather than just masking pain. Warm compresses and anti-inflammatory pain relievers can help you feel better while the swelling settles. If you are using a decongestant spray, keep it to a short course to avoid rebound congestion.
When should you worry about a sinus headache?
Seek urgent care if you have severe headache with confusion, fainting, a stiff neck, new weakness, or sudden vision changes. Also get same-day evaluation if one eye is swollen or painful, or if you cannot move your eye normally. Those signs can point to problems that are not a routine sinus infection.
Can labs help if you keep getting sinus infections or sinus headaches?
They can, especially if you are frequently sick, unusually fatigued, or have symptoms that suggest allergies or immune issues. Depending on your history, a clinician might check for anemia, inflammation, or other contributors that make recovery harder. If you want a convenient starting point to bring data to your visit, VitalsVault offers lab testing options that can support that broader conversation.
