I have breathing issues for the last 2 and half months. last year i had breathing issues for 3 months and this year also the same three months iam suffering from breathing issues. I have done RTPCR swab test and it is negative. I have done CT chest and Blood test. Kindly guide me in this. My ESR is 6mm/hr and
CRP is negative. I have bronchial asthma problem also. Is this infection due to seasonal flu?
