I don't know exactly what your surgery involves, but mine involved tearing up the ear drum to perform surgery in the middle & inner ear, then it had to be put back together. I had packing on both sides of the ear drum for about a week. Then the outer packing was removed, and the it took a few more weeks for the inner packing to "dissolve".
I had a lot of anxiety while the packing was in, because it felt very clogged and puffy, and also I was completely deaf from that ear, plus all the tinnitus roaring.
I couldn't wait to get the packing out. There are times when I'd get panicky about it.
I didn't need a lot of pain meds however, so I ended up not using much of the Vicodin that had been prescribed to me.
