I already have the cortisone injection scheduled! For Friday the 13th; good thing I'm not superstitious, lol! They will shoot in lidocaine or marcaine or something, too, so it should help right away, before it aches for a while and then the benefits kick in.
I called the neuro department, and was told that it's still under review. I called my insurance, and found out that the nurse from the neuro dept. called them today, so I should be getting a call to schedule soon.
