I had an MRI on my brain in May (not an MRA) and a 2nd MRI on my spine (C1-C4, I believe) in July. I am not sure about whether or not they checked for a mastoid effusion. I've also had 4 CAT scans on my brain and one on my left ear. I had a lumbar puncture, which ended up leaking and then required multiple blood patches to fix it. I also had some eye tests where I was told they were checked behind the eye to make sure the levels of my cerebrial fluid were not too high/low. I've had 2 x rays (head and spine) and a dopplar on my circle of Willis. I've had multiple visits and tests to 4 different ENT's (not for 2nd opinions, they refered me to each other) and I have a 6th visit coming up next Tuesday on Sept 27th. I also had my 4th session of acunpuncture performed last night and have my final one scheduled for next week.

There are also a couple of other symptoms which I failed to mention in my initial post:

-The feeling like my head is too heavy for my neck:
It feels like my head weighs 100 lbs and it's difficult to keep it up/straight. It feels better when I tuck my chin down and stretch it out, but doing so makes the pressure in my head increase. I was told I had limited range of motion and the muscles in that region were stiff but they were unsure of the cause. They theorized that the possible reason was that I was subconsciously holding my head in an unusual position because allowing it to sit forward slightly caused the pressure in my head to increase.

-Pressure in specific spots on the left side of my head:
It feels as though the blood vessels (guessing) are inflating like balloons on the left side of my head. I can touch the exact spots and they do seem different than the other side of my head. These areas also suffer from the weird sensitivity issues I mentioned above. So whenever I touch them it sends a vribratory impulse sound/sensation to my left ear. Even the slightest touch does this, including only touching the hairs on my head at that site. Adding cold helps the pain a little.

-Flushing in my head:
The color of my head is red and prone to flushing on a daily basis. This gets worse/better depending on if I have my neck bent, or if I am sitting/standing, laying down, or even laying down with my head slightly arched upwards. They worked on my neck in vestibular testing and that has been the only treatment I've had that has helped with the flushing and the increased temperature in my head. But the problem still exists to this day.
