I think we all do from time to time : )
Even tho u may not have the typical symptoms, do get tested for EDS as so many do not want to push for this as it is one more thing to contend with, BUT it is something that if u do not may make post op recovery more of an issue...so do have this ruled out by testing.,
Here is a link to another thread where I explained the difference of a reg MRI and a CINE...if u still do not understand let me know : )

As for CINE's being available...no not always it depends on where u r, if it is a smaller town it is possible there is no one that knows how to read them let alone have techs or the machine to do them.....so u may have to call around or travel to a larger city.
