SuzeQ,
I had this going on prior to my first fusion (C3/C4). I had never had this in my life! But my PM explained that the next is like a fusebox...full of wires (nerves). When they are compressed as in arthritic facets, they "crosstalk" to the auditory nerves. I thought I was losing my mind...it was all the time. Plus, it SEEMED the anti-inflammatories meds made it worse. Anyway, after the fusion the tinnitus completely stopped. So, what Printerhead said about his fusions is pretty close to what I experienced. And I could hear my heartbeat loud and clear...that kept me awake at night.

Then this past September I had the C5/C6 fused but it was the higher level that caused the tinnitus. All gone now though, thank goodness! I hope the med(s) work for you.
