Jewels,
They can do a Doppler Ultrasound of your legs, and your neck veins to look for reflux of blood. In the neck it is the vertebral veins, not the jugular veins per se, but the internal ones.

It is harder to look for this compromise in the neck, but an experienced doctor can read them, to make a dx of Ccsvi.

JMO, Right now Ccsvi is just Dr. Zamboni's hypothesis to connect this to MS. Even though he has done many tests on those with/without MS. I believe he has bought this to the annual medical conference this year. This is just all my opinion, btw.

It would be great to find a cause for MS and be able to treat it.
