Eric, been studying and researching some notes taken from information that you have provided.
With this and your last hearing test showing a very small hearing loss - hundreds of possibilities can be crossed off because they don't pair with your goings on - there's only a few things left to consider. I will discuss four that may top the list.
http://www.dartmouth.edu/~rswenson/NeuroSci/chapter_7B.html I often use Dartmouth data.
The spinal trigeminal nucleus caused from weakness of the lateral pterygoid muscle from injury.
The second - fourth possible is in ( purple titles) in this link. They are:
The vertebral Arteries. Below that:
The vertebral and Deep Veins. http://www.chiro.org/ACAPress/Cervical_Spine_Trauma.html
X Rays won't make T worse.
I would consider taking to your doctor about getting a
MRA test. It's just a little ultrasound device that's moved around your neck.
I think there's a good chance that T can tossed out the window with treatment. We just need to find the exact cause. I don't see any of the possibilities that may going on as untreatable.
I would try to use correct posture and control extreme neck movements in any direction. It's difficult to do this as I know. Lets stay in touch.
