Hi Dear ,
Welcome to HCM.
Understanding your concern.
Thanks for your query . The
post nasal drip and dry cough can occur due to many reasons like upper
respiratory tract infection ,
sinusitis ,allergy and blockage of nose.
or proper treatment its extremely important to understand the underlying cause of it.So i would suggest you to consult ENT specialist (EAR,NOSE,THROAT) for proper examination and to find out the underlying cause .Doctor may order
blood test ,throat swab test and X-ray.
After proper examination doctor can prescribe antibiotics/
antiviral medicine depending upon the cause and decongestants .
For now take steam twice a day , take over the counter antihistamine drug like benadryl, do warm saline gargles and drink warm water with a spoon of honey mix in it .
Hope your concern has been resolved.
Please write a review about your experience with me and do click at i find this answer helpful if its valuable for you.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
