Post COVID Query. Covid test again?

Hi , I was detected COVID posting on 9th July 2020. I was mildly symptomatic and was in hospital for 10 days . After under observation for 10 days I was in Home Quarantine for 14 days. I didn't develop any symptoms so far . I had little heaviness in the right side of the chest which is also not regular and I feel sometimes . I got myself "Healthy Lung & Body Checkup,Covid Antibody IgG " test from medlife and all the results are fine. I have also developed reactive antibodies but in the discussion with doctor I came to know that this Lung test don't reflect any issue caused to lungs due to COVID. So I want to be sure that I am absolutely fine now and no damage done to me Please if you can assist / guide me. Also do I need to undergo COVID test again ?
