I was diagnosed with covid on april 24th and got negative on may 22 . Today on june 23th i Still have mild  cough with phlegm(usually in the morning immediately after waking up) . I sometimes feel mild strain in my chest when i sit on a chair taking back support. One doctor prescribed me pulmoclear and other prescribed montek lc. What medication should i take to get rid of these post covid problems. Thanks.

Continue pulmoclear and montek lc for 7 days.
