Sinusitis (also called a sinus infection) occurs when the tissues lining your sinuses become inflamed or swollen. Your sinuses are air-filled spaces in your face and head that normally drain mucus to keep your nasal passages clear. When drainage is blocked, bacteria, viruses, or fungi can grow, leading to infection and discomfort.

Sinusitis can be acute (lasting a few weeks) or chronic (lasting 12 weeks or longer). Many patients experience recurring episodes that significantly affect their quality of life.

Who is this service for?

Sinusitis treatment at Denver Allergy & Asthma Associates is ideal for patients who experience:

Frequent or persistent sinus infections
Chronic nasal congestion and facial pressure
Symptoms that don't improve with over-the-counter medications
Recurrent infections affecting work, sleep, or daily activities
Suspected allergies contributing to sinus problems

Our specialists often see patients whose sinusitis is triggered or worsened by untreated allergies. We address both the underlying cause and your symptoms.

What to expect during your visit

During your appointment, your specialist will review your medical history and symptom patterns. They may perform a nasal examination using a small, lighted instrument called a nasal endoscope to visualize your sinuses. Imaging studies (such as a CT scan) may be recommended if needed to guide treatment decisions.

We'll discuss your symptoms, triggers, and any previous treatments you've tried. This helps us create a personalized plan tailored to your needs.

Treatment and management options

Treatment depends on the cause and severity of your sinusitis. Options may include:

Nasal saline rinses and decongestants to relieve congestion
Prescription nasal sprays to reduce inflammation
Antibiotics if bacterial infection is present
Allergy testing and treatment if allergies are contributing
Referral to an ear, nose, and throat (ENT) specialist for advanced cases

Many patients find significant relief by addressing underlying allergies, which can prevent future sinus infections from developing.

Understanding sinusitis and how we can help Q & A

Acute sinusitis typically lasts a few weeks and often follows a cold or upper respiratory infection. Chronic sinusitis persists for 12 weeks or longer, even with treatment. Chronic cases may be caused by allergies, structural issues, or ongoing inflammation. Your specialist can determine which type you have and recommend appropriate treatment.

Yes, allergies can significantly contribute to sinusitis. When you have allergies, your nasal passages become inflamed and congested, which can block sinus drainage and lead to infection. At Denver Allergy & Asthma Associates, we test for allergies and treat them to help prevent future sinus infections and improve your overall sinus health.

Not all sinusitis requires antibiotics. Many cases are viral and improve with supportive care like saline rinses and decongestants. Your specialist will examine you and may recommend antibiotics only if bacterial infection is suspected. We focus on identifying the underlying cause to provide the most effective treatment.

Consider seeing a specialist if you experience sinusitis more than four times per year, symptoms last longer than 12 weeks, or over-the-counter treatments aren't helping. Recurring infections may indicate an underlying allergy or structural issue that a specialist can identify and address effectively.

Please bring your insurance card, photo ID, and a list of current medications and supplements. If you have recent imaging (CT scans or X-rays) or records from previous sinus treatments, bring those as well. This helps your specialist understand your complete medical history and provide the best care.

Relief timelines vary depending on the cause and treatment type. Some patients feel better within days of starting treatment, while others may need several weeks to see improvement. Chronic sinusitis often requires ongoing management. Your specialist will monitor your progress and adjust your plan as needed.
