Hello Docs, Need ur important second opinion, please help. I visited ENT today because I am suffering from common cold and obviously cough and lot of post nasal drip. Almost all th symptoms are subsided except post nasal drip. Doctor suggested me for X-ray, and it came out to be left maxillary sinusitis. I have attached the X-ray and the report. Doc suggested me to take few medications to see if it goes away naturally, on Tuesday they will perform nasal endoscopy to check if it flushes out. Or else they will perform surgery through nostril. I hope this is not very serious condition, please help
