Waiting out a cough...🥴

Anyone ever get sick and develop bronchitis or something similar with a cough? About 4 weeks ago I did my last rowing interval session and developed tons of fatigue, then fever. Fever subsided after a week, then came a cough and fatigue. Now like 1.5 weeks later and im pretty much completely fine, except for a cough that if I start breathing too hard acts up and I go into a coughing fit. Its all a dry cough, just more like my lungs get irritated by excessive heart rate and makes me start coughing a lot. I have been able to weight lift, but haven't even entertained the idea of rowing for the coughing issue. Agh, its annoying. Anyone ever dealt with this? How do you get back into it without stirring up the cough worse? Im assuming not intervals but maybe a short zone 2 session eventually.
