I have a theory after doing a bit of research on CCSVI and common symptoms of MS including anxiety, ear problems, constipation, etc.
Doctors are currently doing a study on CCSVI (if you aren’t familiar, see here http://brain.hastypastry.net/forums/sho ... 418&page=2
) and they found that all folks diagnosed with MS had blockages in either one of two areas. One is the jugular vein and the other is a vein in your back called the azygos.
Well, back to my theory. The jugular vein and the vagus nerve (which causes anxiety) both leave the skull through the same foramen (or ‘skull hole’ - http://en.wikipedia.org/wiki/Jugular_foramen
). I think that the jugular is blocked often at the level of the foramen and squeezes or redirects the vagus nerve against the skull and causes irritation or damage.
The vagus nerve links the ear (hearing loss, tinnitus), the thyroid (low body temp in my case), heart/lung/ stomach/diaphragm (anxiety), and large intestine (many MS folks have constipation).
