Disclaimer: I'm just a patient...
There came a time after I had had fairly mild "MS" that I started to become disabled. I was told (I now think long before they would have been correct) and it eventually was true (I believe they had identified that I was beginning to visibly progress), that I had "converted" to some more progressive form of the disease. It's more gradual, but you can see where it's headed.
A profound change came in the way people related to me. After a while they give up on you, inevitably before you have given up on yourself. Yes, I can't walk much, or work, or drive, or play the guitar. But I have not become a different person. It's just that if you are unable to participate in most normal activities, or need help with ordinary tasks, people can't connect you very easily into their lives anymore.
I think nothing that has been found so far will halt progression, prevent "conversion" to progressive disease, or reverse disability. That has been claimed for various treatments, but I think CCSVI and diet are at least as, or more likely, to do this than, say, autologous stem cells, or a pulse of chemo, or Tysabri, or Gilenya.
There is no guarantee that any of them will. There are statistics, but have you met one? I haven't. There are always deviations from the mean, in everyone. You should decide for yourself whether to stay the conventional course or not, but I think you have at least as good a chance with diet and treatment of veins. That is only my opinion, but I think most agree that the sooner you treat "MS", the better.
I'll leave it for others to tell you about people hurrying you up by pulling on your walker, and other pleasantries. You may get used to being polite about a lot of things, and saying thank you much more than please. Keep saying please. It comes with the territory.
In the short run, don't go off DMDs, as you may not have the option of starting them again.
