Although it has been 20 days, and I have been negative for a long time, I still cough non-stop, and there is still phlegm in my throat. Today, the cough suddenly became a bit severe, and I felt a little muscle pain. I sat on the chair and typed. The time is really unbearable, so please take a day off and resume normal updates tomorrow.

By the way, I actually bought dextromethorphan, which can relieve cough centrally, and ambroxol hydrochloride, which reduces phlegm. But I didn’t take it because I didn’t feel that my cough was too severe. I thought it would be better in a few days. Yes, but now it seems that if you don't take medicine, you still can't do it.
