In this situation, it is recommended to reduce the amount of mucus draining from the nose to the throat. You can do this by using a saline solution and a syringe without a needle. Administering 5 to 10 mL per nostril, 3 to 5 times a day for 5 days can help. Additionally, giving a warm spoonful of honey before bedtime and during coughing fits can also provide relief. It may take 1 to 2 days for this technique to fully take effect.
