My relative has been experiencing severe back pain for the past three days and the doctor suggested an HRCT scan to check for Covid-19. The results showed a few parenchymal fibrotic bands, but everything else looks normal. I'm quite concerned about what this could mean. Could you give us some advice on what steps we should take next, or if theres anything specific we should be cautious about?

it is normal only, if you are having symptoms related to breathing, kindly consult a pulmonologist
