I have it, and I agree, it's extremely annoying. Especially if you're alone in a quiet place. I was told to consume Bilobil (a Ginkgo biloba medication) which is also used for memory loss, Pentoxifylline and vitamin B, but no effect. Doctor advised me to consume them for 4 weeks, I did for 5, yet no result. It sucks, and I've had it for four years. I think I'm used to it now. I can only hear the noise if I'm in a very quiet place though, or if I think about it. If I don't, I don't hear it. Are you serious that there is no cure? What about operation?
