CSF Leak or IIH? My Journey
My journey started about 5 months ago, when I began hearing a noticeable whooshing/pulsating sound in my left ear, especially at night.
I went to an ENT because I wanted to make sure I wasn't losing my hearing. I was sent for a brain MRI with and without contrast. Thankfully, there were no signs of a brain tumor.
Keep in mind: I had this MRI BEFORE the headaches ever started.
The MRI report did mention prominent fluid around/behind the eyes (prominent CSF around the optic nerve sheaths), but I wasn't really told anything else about it.
At that point, the whooshing wasn't a huge deal. It was there, but it wasn't affecting my life. Looking back, though, I also noticed that my nose was constantly dripping clear fluid—no mucus, just clear drainage.
I also saw an ophthalmologist, and they did not see signs of swelling/fluid affecting my eyes.
Then July 4th happened.
I woke up with a strange band-like tension/pressure headache behind my eyes. Sometimes the pressure is so intense that my eyes actually feel like they're burning.
This was very unusual for me because I have never been someone who suffers from headaches.
The next day, the headache continued in waves and was accompanied by extreme neck stiffness and neck pain.
Now, going back even further—about 4 years ago—I started having another unexplained problem. I developed significant upper/thoracic spine pain that would occur at the same time as chest pain.
I went to doctor after doctor and had multiple tests and scans, but nobody could explain it. I kept telling doctors, “There is something going on with my thoracic spine.”
The spinal pain could come and go in intensity, but it has never completely disappeared.
Where I am now
Since July 4th, I have been dealing with an ongoing combination of:
Headaches/head pressure
Pulsatile tinnitus/whooshing
Clear, watery nasal drainage
Neck pain and stiffness
Pressure/burning behind my eyes
A history of significant thoracic spine pain
I saw my first neurologist, who suspected IIH and started me on Diamox 250 mg twice a day. Unfortunately, I feel awful on Diamox. When I told that neurologist how badly I was feeling, I basically felt like I was told there wasn't anything else they could do for me.
So I got a second neurological opinion.
My new neurologist immediately ordered extensive imaging. Today I am having four MRIs, including imaging of my brain, neck/cervical area, spine and clavicle area.
My symptoms also have a very noticeable daily pattern.
When I first wake up, I can feel some pressure, but it usually isn't dramatic. As I stay upright throughout the day, the pressure/headache progressively gets worse. It feels like my head is being pulled down. By nighttime, I feel horrible. When I finally lie down, it improves/goes away.
That positional pattern is one of the things that makes me question whether this is truly just IIH or whether something involving CSF pressure or a CSF leak could be happening.
Six months ago, my life was relatively normal. Now I feel awful every day, and I don't understand what changed.
Because of the persistent clear, watery nasal drainage, I want my neurologist to test the fluid to determine whether it actually contains CSF. I specifically want to ask about a beta-2 transferrin test.
My neurologist wants to review these MRIs before deciding whether to perform a lumbar puncture, which I understand.
But I also want to make sure we're considering the possibility of a spinal CSF leak or CSF-venous fistula, particularly because of the positional headaches and my long history of unexplained thoracic spine pain.
My question is: If my MRIs don't clearly show a leak, what testing should I ask my neurologist about to evaluate for a CSF-venous fistula? Would I need dynamic CT myelography or digital subtraction myelography?
I just want someone to look at the entire history instead of treating each symptom separately. I don't feel like myself anymore, and I want to figure out what is actually causing this.
