Slow, Cyclic Pulsatile Tinnitus?

Hey all,

I can't seem to find any information about this on the web or Tinnitus Talk. I've been getting a slow cycling, high frequency ringing as of the past couple weeks. It's bilateral but won't always be in both ears.

By slow I mean the cycle is 5 - 10 seconds of varying loudness of a high frequency ring (above 6 kHz). It comes on more in the evening and goes all night, over and over. This doesn't sound like typical pulsatile tinnitus. My heart rate is not 0.2 Hz!

Anyone have this issue? I have been diagnosed with cochlear hydrops a few months ago but it's been almost all low frequency issues below 250 Hz, no cycling up high.

Thanks for the help.
