My Sister Has Meniere's Disease In The Left Ear And

My Sister has Meniere's disease in the left ear and for the last 2 years she has seen many ENT's and is scheduled to go to a Neurologist in about a month. She is exhausted all the time, has ocular migraines, vertigo and nausea constantly. We went to a Meniere's specialist and he thought that probably several things were going on but also though she has migrainous vertigo. I am just trying to explore other possibilities and thought about Fibromyalgia. She has depression, very emotional, exhaustion, insomnia, headaches. Trying to get more information. Thank you!
