Oh Ann, you poor thing. I'm so sorry that this has happened to you and that you're not feeling well. Since everything regarding CCSVI has already been said, I'll offer another perspective -- you might want to explore some other avenues of help alongside waiting/watching for doctor appointments and new developments regarding CCSVI.
People with diagnosed and suspected "MS" have had MRIs ordered to check for lesions, but for many of these people, spinal X-rays, to check for structural problems that cause nerve/vein/artery impingement and/or compression, have not ever been ordered. If you've never had spinal X-rays taken, now would be a good time to ask your doctor to order them.
One avenue to explore regarding neuro symptoms caused by structural spinal problems (as shown on X-ray) is chiropractic medicine. The thread
CCSVI and CCVBP was started by Dr. Flanagan (uprightdoc) and is chock full of important information. When you are able,
after you've rested, you might want to read through the thread, most especially if you ever have had injury/trauma to your neck/back, such as whiplash, for one example.
You deserve to see if chiro, specifically upper cervical spine adjustments of the Atlas (C1) and Axis (C2) vertebra, might be right for you. It certainly won't hurt to ask Dr. Flanagan for his opinion on your case.
I hope you start feeling better ULTRA-SOON!
