I had surgery about a year ago on my chest, and ever since sometimes I start to salivate a lot and my saliva is kind of stringy and has lots of bubbles in it. Sometimes it hurts my lungs to breathe, but not every time, and occasionally I dry-heave a few times then feel fine. What could this be?
Thanks for your question after lung surgery there can be excessive sputum or phlegm production because of the inflammatory process or due to a secondary infection regarding excessive salivation its more common in child Chat Doctor.
