I get chest stabbing even after my cough subsides. Why?

Hello doctor,

I had a cough since the start this month, but it was just a dry cough. It has got severe when the quarantine started and I could not schedule anymore consultation. I had taken mucolytic which gave me severe coughing but it released a lot of phlegm yellow or greenish color. I tried calling my friends who are nurses and I got a doctor whom I consulted and gave me prescription of Co-Amoxiclav. I had no fever, chills and night sweats. I have a chest stabbing pain for more than two weeks now. Today, the pain level for me is 5-6 whenever I clear my throat or cough a little. I have taken Co-Amoxiclav 625 mg three times a day for the past one week, but the pain did not go away. But my cough stopped and I had just very few episodes of coughing usually when I wake up. My throat does not hurt or itch anymore but I am more bothered by the chest pain now. The inner pain started before just below my breast on the right, but now it is nearly on the chest itself but still on the right. Please advise.
