Is tinnitus that has lasted for three years truly an incurable disease?

About three years ago, after experiencing a high fever for two days due to a positive COVID-19 test, I suddenly felt deafness, and since then, I have developed tinnitus. It's not just tinnitus; I also suffer from dizziness, and eventually...

After being diagnosed with Meniere's disease at a nearby ENT clinic following an examination, I took medication for six months.

It seems to be getting a little better, but on tiring days, the tinnitus is louder than usual and repeats more frequently.

YouTube and other knowledge-sharing platforms suggest that tinnitus does not go away. Some also say it is a psychological issue.

I regret not going to a hospital specializing in tinnitus when I first developed the condition.

Should I go to a tinnitus specialist hospital now?
