Feeling of a foreign object in my throat for several years... and a sensation of phlegmㅠ

It's been a long time since before COVID-19.

My throat has been uncomfortable as fine dust levels have worsened.

When it gets a bit worse, they say it's pharyngitis when you go to the hospital.

They said it couldn't be long-term like this for more than a few months.

I've been feeling uncomfortable all along.ㅠㅠ

Usually, when you have phlegm, you cough it up loudly, right?

If I do it that way, it doesn't come out, and it feels like I have persistent sticky mucus in my nose, as if I have sinusitis.

The neck area is like that.ㅠㅠ

Sometimes when I eat spicy food, it feels refreshing and I don't feel any foreign sensation, but it's almost like that for nearly 24 hours.

No matter how many times I go to the hospital, there's no special news, and I just continue living uncomfortably.

Are there others like me? T_T
