Pseudotumor Cerebri Support Group
Pseudotumor cerebri (PTC) is a neurological disorder that is characterized by increased intracranial pressure, in the absence of a tumor or other diseases affecting the brain or its lining. Diagnosis requires brain scans and lumbar puncture. Characteristic symptoms are headache, transient visual obscurations or transient visual loss in one or both eyes usually lasting...

to show the docs that regardless of what they think, you have a disorder of elevated ICP.
one thing you can do. do you have lower leg swelling? 77% of us do. my cardiologist gave me Lasix for that, and lo and behold it treated my headaches and brain fog! it is a med used in PTC. so there are other ways to get it.
if you have auditory hypersensitivity, ringing in your ears, or dizziness, go to an ENT and ask for an otoacoustic emissions test to look for damage to your cochlea. get them to diagnose you with Meniere's disease, which is caused by elevation of pressure in the endolymph in the inner ear. (I'm sure this is related to PTC but they are all clueless. endolymph is contiguous with CSF) the treatment for Meniere's is.....Diamox.
hopefully the neuro-ophth will treat your papilledema regardless and this will treat your other symptoms too.
and unless you go on a major hunt for it to find it and treat it in a way that does not increase your ICP (CPAP causes problems), you may not find it and your docs won't buy it. I was treated horribly by doctors when I started this journey, told there was nothing wrong with my sleep study or my airway. well, a couple years later they are all eating crow because jaw surgery for OSA put my PTC into remission. Dr. Larry Wolford in Dallas TX saved my life.

if you read this paper, they discuss several patients whose paps improved after treatment of OSA, who did NOT have elevated ICPs while awake. they had ICP spikes during apneas while asleep.
OSA causes inflammation.
if you want to prove it to yourself, get yourself an aveoTSD tongue retaining device. once I was able to keep this in my mouth all night long, my life changed, and I stopped listening to stupid doctors because I knew what the problem was even if they didn't. I think it works because it pulls your tongue off your jugular veins to allow CSF to drain and it treats the OSA without causing a valsalva which just increases ICP (CPAP does this, and BiPAP to a lesser extent).
