Went To An ENT For A Ringing In My Ears

Went to an ENT for a ringing in my ears he gave me a hearing test which indicated hearing loss in only two frequencies which is unusual It was slight other wise my hearing is good in the affected ear He put me on Prednisone for two weeks and said if the ringing and hearing didn't improve he would have an MRI done to make sure it wasn't a tumor!He said it was a longshot but Jeez sounds scary
