a questions about symptoms and ccsvi

[javabean]

My sense about improvements after CCSVI is that things like balance, cognitive issues/memory, improve moreso than issues having to do with leg strength, leg spasms, and pain (in the legs). Does anyone seem to see that pattern and if so, does it mean the less likely the legs are to improve? In a way it seems logical for balance, etc to get better because if the brain is clogged with blood it may more readily effect cognition and balance. But how does a brain backed up with blood effect the legs? Once again, throwing this out there because my problems are in my legs and my proceduere is coming up in a little more than a month.
Thanks!
