If you’re feeling pressure in your head, stuffy, or tired all the time, you may be asking: Is it a sinus headache or allergies? These two issues share many symptoms—but they need different treatments.
At Pacific Allergy and Asthma, your trusted allergy doctor in Mission Viejo, we often help patients who are unsure of what’s causing their discomfort. Knowing the difference between sinus headaches and allergies can help you feel better faster—and avoid unnecessary treatments.
In this guide, we’ll explain how to tell them apart and what to do next.
What Is a Sinus Headache?
A sinus headache happens when your sinuses—the small air pockets in your face—get inflamed or infected. This causes pressure and pain behind your eyes, cheeks, forehead, and even your teeth.
Common signs of a sinus headache:
- Deep, constant pressure in your face
- Pain that gets worse when you bend over
- Stuffy nose with thick, yellow or green mucus
- Fever or fatigue
- Pain in your upper teeth or jaw
Sinus headaches are often caused by sinus infections. These may happen after a cold or as a result of ongoing sinus problems.
What Are Allergies?
Allergies happen when your immune system reacts to something harmless—like pollen, dust mites, or pet dander—as if it’s a threat. This triggers symptoms like sneezing, itchy eyes, or a runny nose.
Common allergy symptoms include:
- Sneezing or itchy nose
- Clear, watery mucus
- Red, itchy, or watery eyes
- Cough or post-nasal drip
- Symptoms that come and go with the seasons or triggers
An allergist in Mission Viejo can test what you’re allergic to and create a treatment plan that gives long-term relief.
