Hi, my father had undergone surgery for Nasal polyps as he has multiple symptoms like difficulty in swallowing and chin area became white and patchy .. He has been stalling that for years now and finally got it done on Aug 2022 .. He is suffering from cough now which just doesn't go away whatsoever have consulted 3 different ENT surgeons and one pulmonologist got tests done everything is normal ... All the doctors say he needs revision surgery and doesn't guarantee the recurrence he is very clean and always follows doctors instructions religiously. We are stuck in this badly and request help to get out of this
