Blood with sputum after wake up. Sputum.

Two years back initially I felt little bit chest pain and high pulse rate. Little bit blood streak also was noticed through sputum particularly at morning after wake up. So I consult with one cardiologist and after some test carried out doctor prescribed me Metolar XR 25. I was not feeling good with it and blood pressure always remaining on lower side, feeling very drowsy but blood still continue coming through sputum. After few months I consult with another pulmonologist and he diagnosed me as spot at lungs due to bronchitis and prescribed me as Tiomate rotacabs inhaler and Fluticone FT nosal spray. Even continuing with these I don't feel good and blood streak still continue through sputum. Finally I consult pulmonologist at CMC vellore , after CT thorax, CT scan and other different test doctor cleared  me and suggest to stop all previous medicine. I also consulted ENT & Gastroenterologist but after different test they also cleared as no problem. Till date blood coming through sputum.
