hi g, welcome.
you will likely get a better response to your first question if you post as a topic in the treatments-ccsvi forum area.
also, re other treatments, have you looked into nutrition? here's one study:
Dietary patterns in clinical subtypes of multiple sclerosis: an exploratory study (2009)http://www.nutritionj.com/content/8/1/36
"Compared to Dutch population the intake of the following nutrients was significantly lower in MS patients: protein (p < 0.002), SAFA (p = 0.002), MUFA (p < 0.002), total fat (p = 0.005), cholesterol (p = 0.01), folic acid (p < 0.002), magnesium (p = 0.002) and copper (p = 0.01). Compared to the daily recommended allowance it was found that the intake of folic acid, magnesium, zinc, copper and selenium in MS patients is below the daily recommendation (Additional file 1.). Total energy intake was lower in the MS group than in the Dutch population (p < 0.05)... From this exploratory study we found differences in magnesium, calcium and iron intake between subgroups of MS patients that may possibly be related to MS disease progression. This is important because no effective neuroprotective treatment is currently available for MS patients."
there's SO much more out there, i can link you up to info if you have not already gotten into the nutrition side of things.
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
