Neck, RAAS, ADH

I have a condition POTS (postural orthostatic tachycardia syndrome). It began 6 years ago, rather suddenly over a few months. Anyway, not long later I developed severe heat intolerance and, due to that, ended up reading here on the MS board. I soon found out I have alot of common symptoms to MS people (and Chiari people). After MRIs, I was found to have cervical stenosis at C3-C5. Way long before POTS I began with tinnitus, facial nerve pain, etc.

My question is, could degenerative changes in the cervical vertebrae, as in causing the neck to "shorten" due to collapses or exaggerated curvature change the blood flow to and from the brain?

Last question (really!): Is there a baroreceptor in this process in the brain that might think there is too much pressure, and would in turn, affect the renin-angiotensin-aldosterone system(or even ADH) to falsely lower the blood pressure and volume? In that sense, have CCSVI people had issues with altered blood pressure and/or fluid hormones?

Thank you so much!
