Sir/ma'am I had covid 2 months back. After 14 days I consulted my pulmonologist he asked me to get my crp CBC and chest xray as my coughing was not going any breathing issue there. My CBC chest x ray everything was okay and clean. Crp was 1.1 but after the coughing went. I started feeling pain on left side of chest in my muscles and rib. It doesn't pain continuously. It only pains when I move upper part of my body in a certain way or bend down or my chest moves and it goes off when I come back to a normal position. Is this serious? How can this be treated? Thanks.
