hello and welcome to HCM, You need to understand that you have a central throat problem which has to be treated in a systematic manner: 1. Since you have stopped smoking and this causes a withdrawal effect, you need to see a ENT who will advice a GI endoscopy and advice on the anti reflux treatment and also advice on the vocal hygiene 2. Whenever you have nose block due to polyp or deviated nasal septum you tend to breath through your mouth which makes your already dry throat further dry and irritating. Your ENT should perform an endoscopic examination and also CT to confirm the diagnoses and formulate a permanent solution to your nose block and eventually your throat dryness remember that the hard work of stopping the smoking has already been done by you so do not worry about these minor hurdle. They will go up literally in a puff! Take care and lots of warm water always Dr Sriram Nathan
