What Causes Chronic Headaches When Diagnosed With Meniere's Disease?

Question: I am a 33 yr old female who suffers with severe headaches for the last 4 years. These headaches last anywhere from a several hours to several days, usually 4 or 5 days a week. The pain is the back of my head and is a pulsing throbbing pain, that gets worse when I stand, cough, yell; or is sometimes even caused by those same things. I have had 2 MRIs which show normal except for chronic mastoiditis and sinusitis. Around the same time the headaches started my vision began to change. I now have esotropia which I did not have until I was almost 30. However, I find it odd that I have 'good days and bad days' when it comes to my eyes. Some days it will not be that bad and other days very crossed. I have had my eyes checked multiple times and have been told that it was likely always there but somehow my brain used to compensate for it. I still feel like all of my symptoms are connected though. I have been recently diagnosed with Meniere's disease for vertigo, tinnitus, loss of hearing, and an itch in my jaw/ear/throat, they also did an MRI of my ears- all was normal. I feel like it may be some kind of autoimmune disorder because around the same time I also started showing symptoms of Vitiligo, and random petechiae on my throat-which never goes away but shows up randomly. Over the last 3 months I also have to add fainting episodes to the long list of symptoms. My doctor is stumped and I know surely she thinks I'm a hypo but honestly these symptoms are getting to be very debilitating and I don't know what else to do.
