Phoenix Sinus Infection Treatment
Many patients with allergies will have problems with recurrent sinus infections, also known as sinusitis.
Sinuses are air-filled cavities inside your skull that normally function to warm and humidify the air that you breathe in. The cavities are lined with the same type of tissue that lines your nasal passages and as such are prone to the same kind of inflammation that can occur with nasal allergies or allergic rhinitis.
If the sinuses become too inflamed and too much mucous builds up inside the sinuses, infection can occur. Sinus infections are commonly caused by bacteria, although molds and fungus can also cause infection especially in patients with allergies to certain types of molds (known as allergic fungal sinusitis). Viruses can also contribute to sinus infections which is why your doctor may not want to prescribe an antibiotic unless you have had symptoms for more than 10 days (the typical duration of a viral infection is about a week).
Common Symptoms of Sinusitis
Symptoms of sinusitis include pressure inside the head, usually beneath or above the eyes, tenderness of the upper teeth, fatigue, bad breath, drainage of mucous into the back of the throat, nasal congestion and occasionally headache. Some patients who have had chronic sinus problems may also describe a loss of sense of taste or smell, especially if they develop polyps inside their nasal cavities. Polyps are benign (non-cancerous) outgrowths of inflammatory tissue into the sinus cavities.

Chronic and Acute Sinusitis
If you have nasal congestion, facial pressure, cough and thick nasal discharge, you may have rhinosinusitis, commonly referred to as sinusitis. Your sinuses are hollow cavities within your cheekbones, around your eyes and behind your nose. They contain mucus, which helps to warm.
- Chronic Sinusitis: Chronic sinusitis, also referred to as chronic rhinosinusitis, is often diagnosed when symptoms have gone on for more than 12 weeks, despite medical treatment. People with allergic rhinitis or asthma are more likely to suffer from chronic sinusitis. This is because the airways are more likely to become inflamed when allergic rhinitis or asthma are present. Sinusitis may also be caused by an infection, a fungus, deviated nasal septum, nasal polyps or in rare cases an immune system deficiency.
- Acute Sinusitis: Acute sinusitis refers to sinusitis symptoms lasting less than four weeks Most cases begin as a common cold. Symptoms often go away within a week to 10 days; but in some people, a bacterial infection develops.
Types Of Sinusitis

Acute Sinusitis
Acute sinusitis is a short-term infection that causes inflammation in the sinuses, often from bacteria or viruses. Phoenix residents should consult a medical specialist for proper diagnosis and treatment.

Subacute sinusitis
Subacute sinusitis, lasting 4-12 weeks, often starts as a cold and worsens due to bacterial infection. Timely treatment can ease congestion, pressure, and sinus discomfort.

Chronic Sinusitis
Chronic sinusitis lasts over 12 weeks and is often linked to allergies, nasal inflammation, or recurrent infections. Comprehensive allergy testing and treatment can provide lasting relief.
Common Causes Of Sinus Issues
-
Allergic Reactions
Allergies inflame the sinuses, worsening sinusitis symptoms. Through advanced allergy testing, we can identify triggers and provide targeted treatments for long-lasting relief.
-
Nasal Blockage
Blockages like nasal polyps or a deviated septum hinder airflow and proper drainage. If you experience blockages, it’s important to seek medical advice.
-
Chronic Sinus Infections
Recurring infections can lead to chronic sinusitis if left untreated. Addressing the underlying causes is essential to prevent long-term sinus issues and improve overall sinus health.
-
Viruses
Viruses often cause sinus infections, mimicking bacterial symptoms and causing discomfort. If symptoms persist beyond a week in Phoenix, consult a doctor.
-
Polyps In The Nasal Cavity
Polyps are painless growths in the nasal passages, often caused by chronic inflammation. Persistent congestion may require evaluation to address potential underlying issues.
-
Deviated Nasal Septum
A deviated septum displaces the nasal wall, causing breathing issues and contributing to sinus infections. Phoenix residents should consult an expert for evaluation.

Patient Testimonials

Staff is professional and always very friendly!
“ After allergy testing, Dr. Shimamoto explained the process and options of allergy injections and answered all my questions. I follow up with Heidi, who is also great! As of now, I’m still doing weekly injections and it’s been easy to get desired appointment day and times. I am happy that I chose San Tan Allergy!”

Lisa Blaylock ★★★★★
“ Watch out for telemedicine appointments. Make sure you have pre-screened for them. Worked with Jackie over the phone. She is fantastic–super patient and professional. Had exam and skin tests ordered by Dr. Shimamoto. He’s happy and efficient. Great practice, just need to be patient with all the delays and possible miscommunications due to all the pandemic-imposed restrictions.”

Extensive Experience in Managing Sinus Problems
The treatment of sinusitis depends on the factors that caused it. The providers at San Tan Allergy and Asthma have extensive experience in managing sinus problems and often work closely with ear, nose and throat (ENT) specialists to provide patients with sinus problems the relief they seek. If allergies are a cause, immunotherapy (allergy shots) may be a worthwhile treatment to explore. Some patients have an allergy to aspirin or other anti-inflammatory medications such as ibuprofen or NSAIDs that can contribute to their sinus difficulties. The providers at San Tan Allergy & Asthma do offer a treatment specifically designed to treat chronic sinus disease associated with this type of allergy.
San Tan Allergy & Asthma offers a variety of testing services and treatments for various allergic and immunological conditions. Our Gilbert allergy doctors can give you the proper allergy testing near Chandler to find the cause of your allergies, and our asthma doctors near Mesa can help give you the proper treatment for better respiratory function. We serve patients throughout the valley including Phoenix, Queen Creek, Tempe, and more. Contact our Gilbert allergy and asthma doctors to schedule an appointment today.
