I really never planned on using this "personal blog" for constantly yakking about my medical health and health issues. But I just wanted to add one more thing.
I came across this today: http://www.necksecret.com/Multiple_Sclerosis.html
Skip the first 3/4ths of the page (blah blah blah). Read the notes and watch the video at the bottom.
It turns out that the neck can produce MS-like symptoms, and it could perhaps even be one of the culprits of MS causes (that might be saying too much, I don't know).
But I can say this. The very first time I got one of those really weird dizzy spells that felt like nothing I've ever felt before, which was the beginning of a couple weeks worth of this same thing recurring over and over again every hour or two or with each deep inhalation of air, that first time it happened, I was sitting on my sofa, with my head tilted way over to the side while I was slouching, and I sighed and twisted my head and pulled myself upright. That's when it all happened. It wouldn't surprise me at all of this was neck-related.
