I hardly cough and when I do, nothing comes up. Had to have a bronchoscopy to get my initial diagnosis (which probed positive). as I could not produce a sputum sample at all. Right now I have no other symptoms, either. My doctor has not said anything about any airway management techniques. I assume that’s because he doesn’t see need at this point. However I see many, many comments here about its importance and it seems to be a universally applied. Should I question my doc?
