Your nasal blockage from AC exposure without a cold is likely due to non-allergic rhinitis, where irritants like cold air cause nasal swelling. The nasal spray you use, probably containing oxymetazoline, provides short-term relief by narrowing blood vessels but should not be used long-term as it can worsen congestion.

🩺 Understanding Your Symptoms

• Nasal blockage triggered by cold air exposure is common in non-allergic rhinitis.
• This condition causes nasal lining swelling without infection or allergy.
• Overuse of nasal decongestant sprays can lead to rebound congestion, making symptoms worse.

💊 Treatment Recommendations

• Limit nasal decongestant spray use to no more than 3 consecutive days to avoid rebound effects.
• Consider saline nasal sprays or rinses to gently clear and moisturize nasal passages.
• Using a humidifier and avoiding direct cold air exposure may help reduce symptoms.
• If symptoms persist or worsen, a doctor may recommend nasal corticosteroids or antihistamines.

🩺 When to See a Doctor

• If nasal blockage continues despite these measures.
• If you experience frequent nosebleeds, severe discomfort, or other new symptoms.
• A specialist in ear, nose, and throat (ENT) can provide a thorough evaluation and tailored treatment.
