The answer to your question will be different depending on who you ask.
Most neurologists don't think CCSVI is pertinent to any MS patient. I found out about all these other practitioners because, after more than 20 years of being told I had MS, my neurologist said I never had MS. That's not all bad as the meds they offer are expensive, have serious side effects and neither they nor the drug companies say they will cure anything.
Dr. Sclafani and his colleagues would check you for CCSVI, but they still have a relatively low success rate and not enough time or patients yet to have standardized on the best procedure(s) for patients so they're still a crap shoot. Some people get miracles right away, but most have less or no success. (I had three CCSVI procedures. I'm a believer, but I'm also clearly a non-responder.)
A holistic dentist (who also looks at patients neurologically, not a general dentist) might think that a jaw malformation or TMJ is the cause.
A chiropractor would look at adjusting your atlas (the bone at the top of your spine), while someone who does neural cranial integration would start by checking the range of movement of the plates of your skull.
So, if I knew then what I know now, I would start with the holistic dentist first and then the chiropractor. They're relatively inexpensive, they won't put you on expensive drugs that don't work and have awful side effects and their rate of complications is relatively low. They're also a good choice if you've worn braces, have a history of dental problems or falls or just have bad posture.
The bad news is that there are too many choices and no clear direction to make your search easier, faster and less expensive.
The good news is that there are a lot of practitioners there who say your symptoms aren't neurologic and that they can fix them. It's nice to have hope, even if you don't have the time and money to visit them all now.
