I have it in one ear, since September, associated with the Fibromyalga. It's intermittent; I'll have it for one day and it's gone for two. Mine isn't ringing,it's more like cicadas. I do have a slight hearing loss in that ear, but it's nothing I notice. It also is associated with a headache at times. I have been checked by the ENT, had an AER test to rule out acoustic neuroma (a bad thing) so tomorrow I call the acupuncturist!
