Sinusitis

What Is Sinusitis?

Sinusitis, also called rhinosinusitis, is the swelling of the tissue lining the sinuses—air-filled spaces behind the forehead, nasal bones, cheeks, and eyes. These spaces produce mucus, which helps keep the nasal passages clean and protects them from dust, allergens, and pollutants.


When the sinuses become clogged and filled with fluid, bacteria can grow, causing nasal congestion, pressure, and pain in your face.

Symptoms of Sinusitis

Sinusitis symptoms can vary depending on the duration and severity of a condition. Common signs of sinus infection include:


  • Cough
  • Fatigue
  • Headache
  • Sore throat
  • Loss of smell or taste
  • Nasal congestion or blockage
  • Thick, discolored nasal discharge
  • Facial pain or pressure (particularly around your eyes, nose, and forehead)


If you're experiencing these symptoms, you might have sinusitis. Identifying and addressing the cause is crucial for finding the right treatment. 

What are the Causes of Sinusitis?

Sinusitis can arise from a variety of factors that lead to inflammation and sinus blockage. Common causes of sinusitis include:


  • Infections: Bacterial, viral, or fungal infections can lead to sinus inflammation.
  • Allergies: Allergic reactions can cause sinus swelling and blockages. 
  • Structural issues: Nasal polyps, a deviated septum, or other anatomical problems can affect sinus drainage. 
  • Environment irritants: Pollutants, smoke, or chemicals may contribute to sinus problems. 


Pinpointing the exact cause of your sinusitis is critical for selecting the proper treatment. If you are concerned about your symptoms, our allergy experts at Premier Allergy TX  are here to help. Let us identify the cause and get you on the path to relief—schedule your consultation today!

Sinusitis Treatment and Diagnosis

Sinusitis treatment options can vary based on the severity of your symptoms and how long you’ve had them. Some symptoms can be treated at home with:


  • Over-the-counter cold and allergy medications
  • Drinking plenty of liquids 
  • Nasal saline rinses
  • Decongestants


If your condition doesn’t improve after ten days, it is better to consult your allergist immediately. They may prescribe the following medications:


  • Antibiotics
  • Oral or topical decongestants
  • Prescription intranasal steroid sprays (don’t use nonprescription sprays or drops for longer than three to five days as it can increase congestion)


If you are suffering from chronic sinus infection, treatments can include:


  • Intranasal steroid sprays
  • Topical antihistamine sprays or oral pills
  • Leukotriene antagonists, such as montelukast
  • Surgery to treat structural issues like polyps or fungal infections


At Premier Allergy TX, we take a personalized approach to sinusitis treatment, developing a care plan tailored to your unique condition and needs, ensuring the best possible outcomes for relief and recovery.

Sinusitis FAQs

  • Is sinusitis contagious?

    Sinusitis itself isn’t contagious, but the viruses (flu, cold viruses, or RSV) that can cause a sinus infection are. To avoid catching these viruses and developing sinusitis symptoms, wash your hands regularly, avoid touching your face, cover your coughs and sneezes, and clean frequently touched surfaces.

  • What foods should I avoid if I’m on a sinusitis treatment plan?

    If you’re undergoing sinusitis treatment, it’s best to avoid eating excessive dairy, alcohol, or any sugary snacks, as these can sometimes increase mucus production and inflammation. 


    Since sinusitis affects everyone differently—causing anything from thick mucus to sinus pressure—staying hydrated can help thin the mucus and ease congestion. It’s a good idea to pair hydration with nutritious foods, and it’s even better to consult your doctor for personalized dietary advice.

  • Can sinusitis go away on its own without treatment?

    A mild case of acute sinusitis can clear up on its own as your immune system fights off the virus. Get plenty of rest and fluids to help your body recover faster.


    If your sinusitis symptoms last more than 10 days, worsen despite home remedies, or you experience severe headaches, swelling around your eyes, or vision changes, consult your doctor immediately for proper sinusitis treatment.

  • What are the different types of sinusitis?

    There are four main sinusitis types:

    • Acute sinusitis is a short-term condition, typically starting with a cold or virus, and often clears up within 4 weeks with proper rest and home care.
    • Subacute sinusitis lasts about 4–12 weeks and may need more targeted sinusitis treatment, as bacteria might linger when your sinuses are blocked or not draining properly.
    • Chronic sinusitis infection lasts for 12 weeks or longer and often happens when swelling, bacteria, or nasal polyps cause ongoing problems.
    • Recurrent acute sinusitis is when your symptoms come back more than four times a year, which can be a sign of an underlying issue, such as untreated allergies or structural problems (like a deviated septum or narrow sinus passages), and should be evaluated by a doctor.

  • Can allergies make sinusitis worse?

    Yes. Allergies can trigger swelling in the nasal passages, which can block your sinuses and lead to allergic sinusitis. Managing this often requires both at-home sinusitis care (staying hydrated, using nasal rinses, applying warm compresses) and lifestyle changes to support your allergy-specific treatment, such as avoiding triggers, taking antihistamines, or using prescribed nasal sprays.
