What could be the cause of persistent ringing in the ears despite medication?

Hello doctor,

I work with kids with special needs. Five days back, a kid screamed in my ears several times, after which I felt ringing in my ears. It is worse in my right ear. I went to the doctor, and he said there was no infection and it would go away in a few days. It did not go. I went back and asked for a prescription for Prednisone because I heard that it could help with noise-induced hearing problems. The doctor prescribed 60 mg a day, so I have been taking 20 mg three times a day. Today was the third day of taking all three doses. I took my third dose for today and then went to bed. I woke up a few hours later, and my ears were ringing much worse. It was much louder. What should I do? Should I stop taking medicine? I also have had a hole in the tympanic membrane in my right ear for years. I have a slight pain in my right ear, which feels different. I have had ear infections in the past that caused tinnitus, but they went away, and I do not think that is causing the problem. I am going to see an audiologist and an ENT. Kindly help. Thank you.
