I Passed an ABR (Audiology Brainstem Response) Test, Yet I Have Tinnitus and Hearing Loss in One Ear

Hello,
I went to the ENT on Tuesday 12/18/18 to have him check out some throbbing in my right ear. He said that it was a blockage in the tube between nose an ear (it eventually subsided).

I also told him my left ear started ringing on the Thursday 12/13/18 and hasn't stopped since then.

He had my hearing checked and he told me I have some hearing loss in that ear.
He then did an ABR test and I passed.

I asked him, "Is this some sort of brain tumor"?
He said, "It was very unlikely".

My daughter-in-law is an MD and said passing the ABR test is a good thing. It would mean "no brain" mass and she also said an acoustic neuroma is very rare.

Does anyone here have a similar problem related to tinnitus and hearing loss in one ear and passing the ABR?

I'm freaking out....

Thank you

Rob
