Dear Breezy,
I understand the feeling of being scared and not understanding what's going on. I don't know how things work where you are but this news certainly should have come directly from your doctor and if I were you I'd call him on that. Obviously you should be given more information about why they think this course of medication is what is required and what the risks of treatment are.
I had steroid injections directly into my eardrum to try to calm down the loud motor sound caused from tinnitus and it did help. Prednisone is a powerful medication with many healing properties when things go wacky.

I'm sorry to hear you are going through all this and wish you much peace.
