My husband has been diagnosed with Meniers disease. The last few weeks he has been having severe singing, opera male or female, peoples voices, swishing sounds. He has had severe veritigo, nausea. The constant singing and voices he has not been able to control, many sleepness nights. Is there any medication he can take to control this? He has had MRI and CT scans, which came up with no answers. Is there new doctors that can treat this condition or have any new information.
