Idiopathic Intracranial hypertension help needed!

My amazing co-teacher and her family are in desperate need of help.  Her husband was diagnosed with Idiopathic Intracranial hypertension. Described as:
Idiopathic intracranial hypertension (IIH) is a disorder related to high pressure in the brain. It causes signs and symptoms of a brain tumor. It is also sometimes called pseudotumor cerebri or benign intracranial hypertension.

The fluid that surrounds the spinal cord and brain is called cerebrospinal fluid or CSF. If too much fluid is made or not enough is re-absorbed, the CSF can build up. This can cause symptoms like those of a brain tumor. 

IIH is classified into these categories:

Acute. Symptoms happen suddenly, often because of a head injury or stroke.
Chronic. Symptoms develop over time. They may be caused by an underlying health problem.
Idiopathic. The cause isn’t known.

Her husband has been trying to get help for a year and a half now. 

There is only 1 doctor in AZ who specializes in this medical area. 

Unfortunately their insurance doesn't cover it and the Mayo clinic can't help them! 

We know a teacher's salary is never nearly enough, so they need help... Sooner rather than later! 

Please help them. Any a donation helps them!
