Pale yellow sputum is coming sometime with light blood and sometime with heavy blood... Sometime i found the blood in nose too... All tests are done but still nothing has been diagnosed... Proper antibiotics are running but every early morning mucus with mix up of blood are there and after that whole day no issues... This bloody mucus is coming only in morning... Not able to understand this is a problem related to ent or plumonary. Few doctors are saying it's a sinus infection or other are saying it's a tonsil in throat...But I found fresh blood in nose too than don't understand what is a exact problem... Looking for solution and advise..
