(Concern) Post-COVID-19 sequelae

I caught COVID this timeㅠㅠ It's my second time, but the symptoms were milder than the first.

It takes about two days for the fever to go away and for me to be able to be active, but the problem is that the phlegm and cough are not improving as time passesㅠㅜ

My throat keeps tickling, and I can't even cough with a refreshing feelingㅠㅠ

I'm still taking hospital medication. The hospital said it could last up to 6 months or soㅠ

I really don't think it will get better until thenㅠ

Will I get better after some time even though my symptoms haven't improved at all??
