Hum much the same Lidia- not like yours. Glad you have had some relief from it though. There's a lot in what you say about otoxicity, though. As we age this becomes more of a reletive burden ,too. To clarify, my tinnitus is, and always has been, a VHF hiss and is principally affected by medications for hi BP- and always present, of late. I have had fluttering ,as in nerve disturbance, but these always stop within seconds and I've never associated this with hum. It may be connected, though- now you mention it, but no way to tell. In my case, I would rather live with the disease rather than a cure by surgeon :~/
