Gallbladder removed 2 months ago, still phlegm cough

Had my gallbladder out and realize that my cough was due to the throat tube. However 1 week after surgery I developed a cough that has phlegm, yellow /green. No symptoms of a cold or flu, just the cough. Has anyone else had this happen? Thank you! Holly

sorry, i can’t help. hope you get better soon.
