Hi Sir/madam, I recently recoverd from Covid, last month. Im having severe productive cough, used many medicines like MontekLC, and cough syrups. Later I used pulmoclear tabltes for 3 days, those 3 day the production of phlegum is less and my cough got reduced, but again it started after stopping those medicines. Currently having Phlegum prblm with a little bit of cough at night times mainly. Kindly suggest any medication is needed to clear out my throat, it is itchy as well.
