Hi, I was infected with covid in April 2021. By God's grace, infection was mild and I recovered at home in quarantine. Few days after recovery I started smelling cigarette smoke even though no one used to smoke in my vicinity. Then, it was said that it is one of post covid complication and will go away with time. It is 8 months now and I still am able to smell cigarette smoke even though no one smokes. It feels like someone is smoking near my face, the smell is pretty strong.  Is this normal? Thank you!
