Hello my friend I am Dr. Arianisa Thanks for your question on HCM Postnasal drip creates an annoying feeling that makes you want to constantly clear your throat. Because the feeling of the liquid in your throat is irritating and contains inflammatory substances, postnasal drip also can trigger a cough, which often gets worse at night. In fact, postnasal drip is the most common cause of chronic cough. Excess mucus running down your throat may also make you feel hoarse and give you a sore throat. Treatment for postnasal drip depends on the cause of the problem. Bacterial infections are treated with antibiotics. Antihistamines and decongestants can help with postnasal drip caused by sinusitis and viral infections. Call your doctor if the nasal drainage is foul smelling, you have a fever, you re wheezing, or your symptoms last for 10 days or more, because you might have a bacterial infection. Let your doctor know right away if you notice blood in your postnasal drip. If medication isn t helping your postnasal drip, you might need to see an otolaryngologist for evaluation, which may include a CT scan, X-rays, or other tests. Hope you get better soon Best regards
