Hello Doctor, My husband had covid and he recovered from cobid on 14th April and later he did some blood test and chest city scan on 14th april and it was showing minimal lung fibrosis. And then he had taken steorid oral tablets for 5 days and symbicort inhaler for 1 month and he crp and d-dimer was also normal. His oxygen level is also normal , even in covid times also and he don't have any breathing problem and also don't have cough. He is doing all normal physical activity without any problem. My doctor said that it will goes in 6-8 weeks. So my concer is that he has recovered from lung fibrosis or we have to do again some test
