Hello You operated for sinus problem some months back. When asthma pump used , relief with vicks massage on chest. Excruciating cough present typically in the night , may be due to these possibilities , these include: 1 Bronchiectasis, even in mild cases these develops these symptoms: Rattly cough producing sputum after colds only , sputum production 10 ml/day. change of position may cause sputum production, Hemoptysis also present . As you are having excruciating cough associated with phlegm , so bronchiectasis may be one cause . Diagnosis can be confirmed by X ray chest , blood for C B C & E S R , sputum for culture and sensitivity test. 2 Tuberculosis may be the next reason of such prolonged cough with phlegm. Diagnosis can be confirmed by X ray chest , blood for E S R , sputum for AFB. 3 Asthmatic allergic bronchitis , this is another such disease which causes such symptoms . Patient usually complains whistling sound , wheeze, shortness of breath ( as already you are using pump for this purpose). In my opinion consult a CHEST & TUBERCULOSIS specialist and get his opinion because in your case physical examination is important. Hope this will help you.
