Is there any relationship between the two?

I ask because my main issues typically revolve around pseudovertigo, nausea, muscle tension around ears and face; all of which culminates with (or is caused by) anxiety...similar to Meniere's Disease.

My sister and I have somewhat overlapping symptoms and she is a sufferer of IIH. As a male, I know I'm NOT a good candidate for IIH.

While there isn't really a good understanding on genetic links between IIH sufferers, is there any relationship between MTBI/ head trauma/ neck injuries and an increase in intracranial pressure?

Every neurologist I visits practically laughs off the suggestion that I might have IIH, so I'm kind of at a loss. I almost want a spinal tap just to rule it out, but no doctor will bother.
