Sir I have recently recovered from Covid. I had mild infection 6/25 in lungs. I have used doxy 100 mg and pulmo clear tablets. I have recovered in home.  I was not having any symptoms now. It is 30 th day since my first symptom started. I did not use any steroids i am not diabetic.  My random blood sugar level is 150. I was having sinus problem from last two years which was resolved. For two days I had post nasal drip which is decreased after using humidifier in home. I dont have any nose block and discharge. Now I am having slight heavyness in my left cheek. I m having slight irritation in left eye and ear. I am not having fever headache or any other problem. I am very afraid of black fungus. Please advice.
