Talk to Pediatrician on Chest Sounds

My son Azzan Khan is only 7 months old. A month nd half ago he had a chest allergy, due to which sound starting coming from his chest. We gave him *Caricef suspension* under the direction of Doctor which did not work at all. The sound from chest was increasing day by day, so i took him again to the Dr. The Dr. prescribed these medicines. 1-Atem 0.5cc + Ventoline 0.5cc + 5 cc normal saline nebulized after every 4 hrs one day, then after every 6 hrs 2 days and then after 8 hrs for two weeks. 2- Clenil 0.5cc nebulize every 12 hourly for two weeks. 3- Syp accephyl 2cc every 12 hourly for 5 days. 4- Syp Zatofen. 5- Tab Deltacortril 2 a day for seven days. 6- Sachet Myteka for 3 months. Now, he is for better than before but not completely well. He still has a whooping cough & the sound of the chest still felt very easily. Note that from the beginning to the end, he never had a fever. Due to COVID-19 i can not even take him to the Dr. Dear Doctors i will be waiting for your valuable comments
