Hi...r u just going to a neurologist? Once u r dx'd with chiari u should be seen by a NS(neurosurgeon)...u also need a well informed NL...so u should ask what they know about chiari...but many times, they do not know all that much.
Have u had all the testing?...A CINE MRI, and MRI's of ur cervical spine, thoracic, and lumbar spine....the lumbar MRI is used to look for tethered cord and a syrinx...and all MRI's should rule out a syrinx in each area.
Many with chiari could have autoimmune issues as well as connective tissue disorders..so u should be checked for them...and sleep apnea.
In the list of disorders u want to rule out...MS, Lupus, Lymes.....Hashimoto's thyroiditis, Ehlers-Danlos syndrome,DDD, scoliosis,bulging disks.....
The NL should do the testing and all the dxing and then send u to a NS.
We do have a list of ?'s for the NS-
