Hi and welcome to the Chiari forum.
Did u get copies of ur MRI on disk? If so, make copies of it and send it to true Chiari specialists for review.....
Many Drs do not recognize Chiari as being able to cause symptoms, and symptoms do cycle so it can be difficult to connect all the symptoms together for one DX.
Many Drs also use out dated info to classify if u have Chiari by the length of the cerebral tonsil herniation.....which as I said is outdated criteria but the info taught in med schools is outdated and minimal.
Chiari can only be classified as Chiari if there is a malformation of the skull, the herniation no matter how long it is...and can be considered to cause issues if there is a CSF obstruction or a related condition exists...
Ur symptoms can indicate not only Chiari symptoms but possibly some of the related conditions....like low vitamin and mineral levels, Vit D, B12, magnesium and potassium....even an auto immune thyroid condition known as Hashimoto's....so more testing is needed to know what all is going on.
A CINE MRI will look for a CSF obstruction, MRI's of the cervical, thoracic and lumbar spine will help rule out disk issues, syringomyelia, tethered cord.....
U will want to locate a true Chiari specialist, use the list of Drs we compiled here in our Health Pages, please note the list is not a referral nor an endorsement....it is only meant to be used as a tool to help u get started in researching Drs. The names are of Drs the members here have been to, treated by and liked...
