Hard to know, Johnnymac. If I were younger and not on Tysabri or feeling that my MS was progressing beyond the RR stage, I think I might want to either participate in a study for the testing only and also try some of the alternatives you mentioned.
I think it's very individual, as to how sick is the person? Dr. Zamboni said, the longer a person waits to have the Liberation treatment, the less recovery will take place.
That prompts me because I've lost a lot. I'm willing to risk, even death, but then i'm older, probably SP, and have little to lose.
Good luck. In the meantime I do take baby aspirin and eat foods to thin the blood. Your question about the veins forming around the blocked veins is an interesting one though - if there's reflux though, then I'd say they aren't doing their job either. But it's always a good idea when you think about thinning the blood to talk to your doctor before beginning any kind of program that would alter your blood flow.
Best of luck to you and your lady.
