I have the tendency to cough out every morning, which sometimes keeps me irritating through the day. The feeling every morning is very irritating and I feel like vomitting also. Sometimes I even feel slight uneasiness in my chest. I had undergone chest X-Ray some months ago and the reports were normal. Sputum and throat swab reports are also normal. I have also had medicines for acidity on doctors suggestion. Even that did not work. Now this has continued for so long (almost two years) I am very scared. Also constant coughing in officrle and other public places is very emabarassing. Please suggest which type of doctors should I approach, general physician, ent or chest?
