Hello,
Your symptoms of nasal blockage, mucus sensation in the throat, and occasional headache for one week are suggestive of rhinitis (nasal inflammation) with postnasal drip.
Possible causes include a viral upper respiratory infection, allergic rhinitis, or sinus inflammation.
Alternating blockage between nostrils can also occur due to the normal nasal cycle, which becomes more noticeable during congestion.
Nasivion (oxymetazoline) provides temporary relief but may cause rebound nasal congestion if used continuously for more than 3â5 days.
Next Steps
Use saline nasal spray or saline rinses 2â3 times daily to relieve congestion and clear mucus. If you have used Nasivion for more than 3â5 consecutive days, discontinue it and consult a physician if congestion persists. If allergic rhinitis is suspected, a physician may recommend an intranasal corticosteroid spray, such as fluticasone or mometasone. An antihistamine such as cetirizine may be considered if associated with sneezing, itching, or watery nasal discharge. Consult a general physician if symptoms persist beyond 10 days, worsen, or recur frequently.
Health Tips
Maintain adequate hydration, avoid dust and smoke, and sleep with your head slightly elevated. For nasal rinses, use only sterile, distilled, or previously boiled and cooled water. Antibiotics are generally unnecessary unless a bacterial infection is clinically suspected. Seek medical attention if you develop persistent high fever, severe facial pain, swelling around the eyes, vision changes, or a worsening headache. Most uncomplicated cases improve with appropriate nasal care and treatment. Wishing you a speedy recovery!
