Why This Matters
Runny nose. Congestion. Head pressure. When your head feels stuffy and you're constantly reaching for tissues, it can be hard to tell what’s really going on. Is it just allergies—or could it be a sinus infection?
At BASS Medical Group, we help patients across Northern California get clarity and relief. Let’s break down the difference so you know when it’s time to see a provider.
Symptoms: Sinus Infection vs. Allergies
Pro tip: If your symptoms last longer than 10 days or worsen after initially improving, it may be a sinus infection, not allergies.
What Causes Each Condition?
- Allergies are triggered by allergens like pollen, dust, or pet dander. Your immune system overreacts, releasing histamines that cause sneezing, itchiness, and congestion.
- Sinus infections (sinusitis) are caused by viruses or bacteria that inflame the sinus linings. They often follow a cold or upper respiratory infection.
How to Treat Allergies vs. Sinus Infections
Allergy Relief:
- Antihistamines (e.g., loratadine, cetirizine)
- Nasal steroid sprays
- Limiting exposure to allergens (e.g., keep windows closed during high pollen days)
Sinus Infection Relief:
- Saline nasal rinses
- Decongestants
- Prescription antibiotics (only if it’s bacterial)
- Warm compresses over sinuses

When to See a Doctor
You should contact a BASS Primary Care Provider (PCP) if:
- Symptoms last more than 10 days
- You have facial pain with a fever
- Over-the-counter allergy meds aren’t helping
- You get frequent sinus infections
Our PCPs can determine the cause of your symptoms and recommend appropriate treatments—or refer you to a specialist, if needed.

Frequently Asked Questions
How do I know if it’s a sinus infection or just allergies?
If your symptoms last more than 10 days, get worse after improving, or include facial pain and fever, it may be a sinus infection. Allergies usually cause itchy eyes, sneezing, and clear mucus, while infections often involve thick nasal discharge and facial pressure.
Can allergies turn into a sinus infection?
Yes. Untreated or poorly managed allergies can lead to nasal inflammation that blocks drainage, creating an environment where a sinus infection can develop—especially after a cold or viral illness.
What are the best treatments for sinus infections?
For viral sinus infections, rest, saline nasal rinses, decongestants, and warm compresses help. If symptoms are severe or persist, your doctor may prescribe antibiotics to treat a bacterial infection.
What medications help with allergies?
Over-the-counter antihistamines (like cetirizine or loratadine), nasal steroid sprays, and limiting allergen exposure (like staying indoors during high pollen days) are effective for managing seasonal or chronic allergies.
When should I see a doctor?
You should see a provider if:
- Your symptoms last more than 10 days
- You develop facial pain and a fever
- Allergy medications aren’t helping
- You experience repeated sinus infections
A Primary Care Provider at BASS Medical Group can help diagnose and treat both conditions—or refer you to an ENT specialist if needed.
