It sounds uncomfortable to have a blocked nostril and excess mucus causing noise in your throat. These symptoms often result from nasal congestion or postnasal drip, which can be due to allergies, infections, or irritants.

• Using a saline nasal spray or rinse can help clear nasal passages and reduce mucus.
• Staying hydrated thins mucus, making it easier to clear from your throat.
• Over-the-counter decongestants might provide relief but should be used cautiously and not for more than a few days.
• If symptoms persist beyond 10 days, worsen, or are accompanied by fever or severe pain, seeing an ear, nose, and throat (ENT) specialist is advisable.
