For what it is worth - I have had MS for 33 years, had all the drugs, needles etc, have been at deaths door, and back again.
I know the symptoms of MS pretty well.
I have angioplasty for CCSVI four times, and after each procedure, all that is left of my MS is drop foot and a limpy leg.
I have come to the conclusion (in my opinion only) that the symptoms of CCSVI Are MS.
The symptoms that I am relieved of post angio for ccsvi are :-
Gross fatigue, unreliable bowel/bladder, dizziness/lack of balance, all over stiffness, heat intolerance, sore lower back, sore base of skull, weak/unsteady tingling hands, vision problems, food/drink catching when swallowing, numb & "buzzing" lips, weak posture, feeling out of sorts, tiny & messy hand writing, short term memory impairment, headaches/eye aches, weak arms.
So, in my experience & in my mind, the above symptoms pretty much embody what MS is.
When these symptoms return, I don't think the treatment has not worked ... I just wish a stent maker would develop a specialised stent for jugular & azygous, so the benefits can be maintained.
I am waiting for Professor Slavin in Tel Aviv to offer his trans-differentiated mesenchymal stromal stem cell treatment, to try and regenerate oligodendrocytes in the damaged leg.
