A chronic PRODUCTIVE cough? Has a doctor explained why you have that productive cough and cleared you? Otherwise, you have not "recovered" from bronchitis. That's evidence of an ongoing inflammatory or infectious process in your lungs until shown otherwise. I know a lot of people avoid doctors like the plaque (especially since as group they swallowed the covid shot Kool-aid), but you don't want to whistle in the dark on this. Lung function is immediately life-critical after all.
