Common Sinus Infection Symptoms and When To Seek Care
Sinus infections often start after a cold or during allergy season, and symptoms may gradually worsen or seem to improve and then return.
Common sinus infection symptoms may include:
- Facial pain or pressure around the cheeks, forehead, or eyes
- Stuffy or blocked nose
- Thick nasal drainage that may be yellow or green
- Postnasal drip (mucus draining down the throat)
- A headache that’s sometimes worse when bending forward
- Reduced sense of smell or taste
- Ear pressure or fullness
- Fatigue or a “run-down” feeling
- Bad breath
- Low-grade fever
Sinus Infection Symptoms That Require Urgent Medical Attention:
- Symptoms lasting longer than 10 days without improvement
- Symptoms that improve, then suddenly worsen again
- High fever that doesn’t respond to typical fever-reducers
- Severe facial pain, swelling, or tenderness, especially near the eyes
- Eye pain or vision changes
If you experience severe trouble breathing, confusion, a stiff neck, or significant swelling around the eyes, call 911 or go to the nearest emergency room immediately.
What Causes a Sinus Infection?
Your sinuses are air-filled spaces behind your cheeks, eyes, and forehead. Normally, mucus drains freely. When the sinus lining becomes inflamed and swollen, drainage can slow or be blocked, creating pressure and the perfect environment for germs to grow.
Several triggers can lead to a sinus infection, so determining the actual cause is essential for getting the appropriate treatment.
Viral Illness
Many sinus infections begin with a virus, such as a typical cold. Inflammation and swelling can trap mucus, leading to congestion and pressure that may last a week or more.
Bacterial Infection
Sometimes bacteria can take hold after a viral illness has already caused blockage. Bacterial sinus infections are more likely when symptoms persist beyond 10 days, become more severe, or worsen after initial improvement.
Allergies and Irritants
Seasonal allergies, dust, mold, and other irritants can inflame nasal passages and narrow drainage pathways, making sinus symptoms more frequent or harder to shake, especially during high pollen times in South Carolina.
Structural Factors
A deviated septum, nasal polyps, or other structural issues can make it easier for mucus to get trapped. If sinus problems keep returning, your provider can discuss whether these factors may be contributing.
How We Diagnose Sinus Infections
When you’re not feeling well, you want answers without the runaround. At Prisma Health Urgent Care, we focus on quick but thorough evaluations, so your treatment plan matches what’s actually going on.
During your visit, our providers may:
- Review your symptoms and how long you’ve felt sick
- Ask about allergy history, recent illness exposures, and prior sinus infections
- Perform an ear, nose, and throat exam for tenderness and inflammation
- Recommend testing when symptoms overlap with other conditions, such as the flu, COVID-19, or strep throat
This evaluation helps us determine whether your symptoms are most consistent with a viral illness, a possible bacterial infection, or another cause, so you get the most appropriate care and avoid unnecessary medications.
