Hi...the symptoms r similar to those of chiari, but it can be also said the same for many other conditions.
I would suggest that u ask for copies of ur MRI and the reports....not all drs feel chiari is a significant finding....
Have someone review the MRI's by a second dr....and look closely at all the info on the report not just the findings at the bottom.
In addition to chiari, there r related conditions like POTS and other's that are affected by increased BP and CSF pressure.
Please keep us posted on what u find out.
