Chest blockage like feeling. My doc?

Consulted for: Mr.Devesh Jakhmola (Myself), Age: 15, Gender: Male Hey Doc I am Devesh and my age is 15 years. I recently started coughing after eating a sandwich. I felt a pressure on my chest and pain on the back while coughing. It felt as if my right chest is clogged but I went to my nearest hospital. They took my X Ray and the doctor concluded that I had come across COVID 19. He gave me some medicines that are Azithromycin, Omnacortil 20, Propan DSR, VITAUP-Q10 multivitamin, electrol juice, Ibuprofen Paracetamol and caffeine tablets, Balm to put on chest , Vicks inhaler , Codeine Phosphate Triprolidine Hydrochloride cough syrup and terbutaline Sulphur Ambroxol HCL Guaiphenesin and menthol syrup. I have no difficulty breathing as it was oregano which went by mistake in my trachea. I am taking steam and the pain has reduced but the pressure is persistent. Do I need to worry or this medication will work ? The pain has reduced but it feels a little blocked. Can I trust my Doc? Thanks.
