Hi doctor, I have completed 2 months of treatment after covid. My initial ct scan showed 30 to 40% lung involvement. It did scan after two months and it showed the improvement. My doctor prescribed me Pirfect 267. I have Started from two days. I am suddenly feeling weekness and tiredness since two day and mild fever ( temperature range from 98.6-99) throughout day I'm last two day. I did antibody test on 1 week of April and it was > 20. I am worried if I am reinfected. What are chance to that ?? Is this tiredness due to medicine also??
