I'm dealing with a wet cough that's been hanging around for about 45 days. I saw a pulmonologist before and was told to take Montek LC, Alerodil syrup, and some antibiotics. I finished all the meds, but the cough is still here, and I hear a whistling sound in my chest. Is there a chance this could be TB or asthma? With the lockdown, I can't see a doctor in person. Which medicine might help ease my symptoms until I can get medical advice?
