Signs and Symptoms of Sinusitis

Sinus infections, or sinusitis, can lead to uncomfortable symptoms that often linger longer than a typical cold. These symptoms may vary based on the cause of the infection but typically involve inflammation and blocked sinus passages.

Common symptoms include:

• Pressure or pain in the face (around the eyes, cheeks, or forehead)
• Headaches
• Nasal congestion
• Runny nose or thick mucus
• Sore throat
• Ear pressure or discomfort
• Postnasal drip
• Fatigue
• Decreased sense of smell or taste

If symptoms persist for more than a week to 10 days, worsen over time, or return after briefly improving, it is a good idea to seek care at AFC Urgent Care Thornton.

Sinus Infection vs. Allergies: What’s the Difference?

Because both conditions can cause congestion and sinus pressure, many patients mistake one for the other. Here are a few ways to help you tell them apart:

• Allergies often cause itchy, watery eyes and clear nasal discharge, and symptoms can last for weeks or months during allergy season.
• Sinus infections usually cause thicker yellow or green mucus, facial pressure, and possible fever or fatigue. They tend to last 7–10 days and may follow a cold or allergy flare-up.

If you’re unsure about which you have, our medical team can help determine the cause and recommend the most effective treatment to bring you relief.

Diagnosis and Treatment Process

At AFC Urgent Care Thornton, our providers take a thorough approach to diagnosing sinus infections. During your visit, we will evaluate your symptoms and perform a physical exam to determine the cause.

Your visit may include:

• Examination of your ears, nose, and throat
• Checking for sinus tenderness and swelling
• Discussion about symptom duration and severity
• Additional testing if needed to rule out other conditions

You will receive high-quality care comparable to a primary care office, without the wait.

Treatment Options

Treatment for sinus infections depends on whether the infection is viral or bacterial:

Bacterial Infections:

If a bacterial infection is suspected, antibiotics may be prescribed to help eliminate the infection and reduce symptoms.

Viral Infections:

Most sinus infections are viral, meaning antibiotics are not necessary. Treatment will focus on symptom relief while your body heals.

Symptom Relief May Include:

• Decongestants to reduce swelling in the sinuses
• Nasal sprays to improve airflow
• Pain relievers to ease headaches and pressure
• Additional supportive care recommendations

Our providers will guide you toward the most effective treatment based on your condition.

What Are the Potential Risks of Trying At-Home Remedies?

Home remedies like sinus rinses can be helpful, but they must be used properly to avoid complications.

One key risk is using tap water in nasal irrigation devices. Tap water may contain microorganisms that are safe to drink but not safe for nasal use, which can potentially lead to infections.

There have been rare but serious cases of complications from improper use, including bacterial infections and exposure to harmful organisms such as Naegleria fowleri.

To reduce risk:

• Use only distilled, sterile, or previously boiled water
• Clean your irrigation device thoroughly after each use
• Follow all safety instructions carefully

If you have concerns about at-home remedies, our providers can help you choose safe alternatives.
