I am 22 years old female. When I was 5, I had asthma, then again when I was 11, I got asthma and admitted to hospital for several days. Now few days ago I dusted my home and went to office in the afternoon but I came home because not feeling well. And the same day, in the evening I got difficulty in breathing. Then I thought I was infected by covid, and took some medicines from pharmacy. But the result is negative. So now i'm feeling breathless sometimes and the mucus or bulgum or cough is not getting out of my mouth, it is just stuck in my throat. And I feel like the holes in my nose are became smaller and the area around the moustache is swollen a little bit. So please tell what should I do and what not to do. I'm really worried because I can't even go to the hospital due to corona.
