Allergic rhinitis and sinusitis are two common conditions that affect the nasal passages and can cause similar symptoms. However, there are some key differences between the two that can help you determine which condition you have.
Symptoms:
Allergic rhinitis is caused by a reaction to allergens, such as pollen, dust, or pet dander, and results in inflammation of the nasal passages. Symptoms of allergic rhinitis can include sneezing, a runny or stuffy nose, itchy eyes, and postnasal drip.
Sinusitis is an inflammation of the sinuses, which are air-filled cavities in the face. Symptoms of sinusitis can include a headache, facial pain or pressure, and a thick, discolored discharge from the nose.
Diagnosis:
A doctor can usually diagnose allergic rhinitis based on a physical examination and a patient's history of symptoms. Allergy testing, such as a skin prick test or a blood test, can be used to identify the allergen that is causing the reaction.
Sinusitis is usually diagnosed through a physical examination and imaging tests, such as an X-ray or a CT scan. A sample of nasal discharge may also be taken for testing to identify the cause of the infection.
Treatment:
The treatment for allergic rhinitis is to avoid the allergen if possible and manage the symptoms with medications such as antihistamines or corticosteroids.
Sinusitis is usually treated with antibiotics to clear the infection, and decongestants or nasal sprays may also be used to reduce swelling.
By understanding the differences between allergic rhinitis and sinusitis, you can get the right diagnosis and treatment to manage your symptoms.
