I was diagnosed a year ago with CM1 at 6mm. I have so many symptoms and they are worsening since car accident when I was diagnosed. However, I was post neck fusion, 4 levels, 2 years, I was never told I had Chiari, but dx with Nystagmus, cluster/migraines, complicated migraines, extreme headaches when I cough or sneeze or strain, Horner's syndrome, costochondritis, condromaltia in both knees, ringing of my ears, and the list continues...sleep apnea, bad-- frequently feeling of passing out, mostly with the pain in head....I have seen PM and they disagree that any of this is Chiari related and that 10-20% of the worlds population walks around with CM an does not even know it. I have cried at several Dr. visits because the pain is so real and the 'episodes' are excrutiating...no migraine meds work. Can anyone please give me any advise and any way to have a CINE MRI, as none of the Docs have even heard of it, or either the one that did said he believed the car accident just made my brain swell and it's probably gone down now. So sad...I need someone who will follow through. this is real! Thank you in advance.
