Hi, I had my covid positive on 3rd May and was on home isolation with just antibiotic, Montek lc and multi vitamin for 10 days. I am not diabetic and dint take any steroid. After 3 weeks from the covid first symptom, I got nose blocked on one side and nasal passage is inflammed with no mucus. Consulted ENT where both endoscopy and sinus CT are performed. He has mentioned that there is no Black fungus evidence in endoscopy but able to see minor infection in sinus. After 1 week, nasal blockage and sinus pressure on one side still persist. Should I be worrying on this if this could be black fungus or any other infection?
