My wife ct scan showed condition as Pneumonitis with score 14/25, also 2nd time covid positive. Initial positive was without symptoms,  after 25days she was in contact with another covid and developed fever and tired. Just took dolo650 for 5days. Later felt it's something else and did ct scan and rtpcr again, now she has difficulty in eating as fever comes often and she feels too much tired, cough comes, once a black phlegm too was present, oxygen saturation yesterday (day of ct scan done)was 91,now improved to above 95 and currently in home isolation. She does not have BP or diabetic. Will this recover without complications or need critical hospitalization?did cbc, crp and its normal.
