The only possible doubt is that the texture of both lungs increases and thickens, but it does not show disorder, and sometimes the lungs are stimulated.
The possibility of inflammation is not ruled out, but even if there is, it is not serious at present. Perhaps because of this, I wrote a follow-up sentence.
Don't worry, if you feel abnormal in your lungs within a few months, go to the hospital or a higher-level hospital for examination.
