Is it common to experience hypercusis after ear wax removal?

I've always had a problem with earwax. When I was a teenager, my ears would often get blocked and I had to insert wax removal fluid and then starting hopping around and shaking myself to force the earwax to drip out.

But I never had tinnitus during these times. I only experienced blockage and silence.

I'm now in my mid 20's. For the past 1 and a half years, I have been using foam earplugs almost regularly for my job.

I had recently gone to the doctor and he said that my ears are fully blocked. I can't remember clearly but I think he used the word "plugged". And I think that means when earwax is pushed back towards the eardrum and solidifies.

After he said this, he use a curette to manually scoop out some earwax from my right ear. And he then gave me some oil drops which I was supposed to use in both my ears regularly.

A short while after this, I started experiencing tinnitus. It was reactive tinnitus. It became worse after exposing myself to sounds. And there is a different type of ringing in my right ear than in my left ear.

My right ear (which he scooped out earwax from) is also experiencing hypercusis.

I have read somewhere that people can experience H after getting earwax removed. My question is - Does this indicate permanent damage? Or is it simply a case of habituation? Because I had earwax for so long, my ears are now oversensitive to noise?
