Sinus Infections: When to Seek Care at Nadora Urgent Care in Greeley

Sinus infections — also known as sinusitis — are a common reason patients visit urgent care, especially during cold and flu season. The symptoms can range from annoying to intense, often mimicking the common cold but lasting longer and hitting harder.

If you're dealing with facial pressure, congestion, or a deep, nagging cough, don’t wait it out. At Nadora Urgent Care in Greeley, we provide fast, accurate diagnosis and same-day treatment options to help you feel better faster.

What Is a Sinus Infection?

A sinus infection occurs when the tissues lining your sinuses become inflamed or swollen.

This inflammation blocks normal mucus drainage, leading to pressure, pain, and congestion.

There are two main types of sinusitis:

• Acute sinusitis: Usually caused by a virus, it typically lasts less than 4 weeks.

• Chronic sinusitis: Lasts longer than 12 weeks and may be related to allergies, nasal polyps, or structural issues.

Both forms can cause similar symptoms, but acute infections tend to come on suddenly and are more common in the fall and winter.

Common Symptoms

Sinus infections can easily be mistaken for colds or seasonal allergies. Here are the most frequent symptoms that suggest sinusitis:

• Facial pain or pressure (especially around the eyes, cheeks, or forehead)

• Thick yellow or green nasal discharge

• Congestion or blocked nasal passages

• Postnasal drip and sore throat

• Headaches or ear pressure

• Loss of smell or taste

• Cough that gets worse at night

• Fatigue or general feeling of being unwell

You don’t have to experience every symptom to be dealing with a sinus infection — even one or two can affect your quality of life.

Causes of Sinus Infections

Sinus infections can be caused by a few different factors:

• Viral infections are the most common and typically resolve on their own with rest and fluids.

• Bacterial infections may develop when viral sinusitis lingers or worsens — this is when antibiotics may be needed.

• Allergies can also cause or contribute to inflammation in the sinuses, leading to chronic or recurring symptoms.

Knowing the cause helps determine the best course of treatment — and that’s where we come in.
