Dizziness and Lightheadedness after Swallowing-Stroke Like Event?!

[Foxyjazz]

I've had problems with my eustachian tubes for a while, wherein they don't open right or sometimes open dramatically and rapidly change air pressure in what seems like my middle ear.  This sometimes happens when I swallow, and it almost feels like a *bang* in my ear, followed by what feels like my eardrum about to blow out.

Usually this only results in muffled hearing and increased ringing for a time.    

Today, however, it was far worse.  I was out for a walk, and I swallowed with the bang in my right ear. After it happened I slowly started feeling dizzier and dizzier while walking and becoming disoriented.  My gait changed and I was kinda dragging the right side of my body, although there was no weakness apparent.  
I recovered a little, but then I swallowed with the same effect again.  I was feeling off all the way home.  By the time I got home, I was feeling somewhat faint, and very dissociated from my visual field, especially the right side; I could see, but it was like looking through a tunnel and I kinda felt like I was in a dream.  Any sudden noise made me feel a little bit like I could faint, and made this unpleasant jolt-like feeling in my right ear (I am guessing this is a kind of hyperacusis).  In addition, my motor coordination is not doing well; sometimes I freeze in a certain position, or in a certain gesture for a few seconds, and I have otherwise been moving very slowly, as if I had extreme insecurity navigating through space.  My right side is also getting some strange tremor-like experiences when I am walking.  Oh and my hearing is worse in that ear, as well as the ear that was not affected.  As a matter of fact the other ear has this strange motorcycle sound in it.

Um, any thoughts about what is going on?!  
I should note that I have been diagnosed with migraines before (basilar, otic), as well as some form of dysautonomia.  But this is not usual for me even with these conditions, and it is freaking me out.
