Is it allergies, a sinus infection, or just the weather? You’re not alone if you feel congested and achy around your eyes or cheeks, especially during allergy season. Sinus pressure is a common complaint here in California’s Central Valley, where pollen counts and air quality make a tough combo for sensitive sinuses. Let’s break down how allergies can cause sinus pressure and how to find relief.
Can Allergies Really Cause Sinus Pressure?
Yes—allergies can cause sinus pressure.
Here’s what happens: when exposed to allergens like pollen, mold, or dust, your immune system overreacts. That reaction causes inflammation in the nasal passages and sinuses. The result? Swelling, mucus buildup, and—you guessed it—sinus pressure.
Common allergy triggers in the Central Valley:
- Grass and tree pollen (especially in spring and early summer)
- Dust from agriculture or dry winds
- Mold spores during damp or rainy stretches
- Pet dander and indoor allergens
When sinuses swell and can’t drain properly, pressure builds up in the face, especially behind the eyes, cheeks, and forehead.
Allergies vs. Sinus Infection: Know the Difference
It’s easy to confuse sinus pressure from allergies with a bacterial sinus infection. The symptoms can overlap, but the cause (and treatment) are different. Did you know that sinus headaches may be an uncommon symptom of an allergy?
Allergy-related sinus pressure usually includes:
- Clear or slightly cloudy nasal drainage
- Itchy eyes, nose, or throat
- Sneezing fits
- Pressure that comes and goes with exposure (like being outside or near pets)
- No fever
Sinus infection symptoms often include:
- Facial pain with thick yellow or green mucus
- Pressure that worsens over several days
- Possible fever or fatigue
- Bad breath or a reduced sense of smell
- Sinus headaches
- Symptoms that last 10+ days or worsen after seeming to improve
If you’re unsure, that’s when our experts at Baz can help you sort it out with testing and a personalized care plan.
Tips for Relieving Allergy-Related Sinus Pressure
If allergies are behind your sinus pain, treating the root cause—your allergic response—is key.
Try these at-home steps:
- Rinse your sinuses with a saline spray or neti pot to clear allergens and reduce swelling
- Use HEPA filters in your home and bedroom
- Shower and change clothes after spending time outside
- Keep windows closed during high pollen or poor air quality days
- Track local pollen counts and avoid peak times outdoors
You may benefit from long-term solutions like allergy testing, immunotherapy (allergy drops or shots), or prescription treatments if symptoms persist.
