I was diagnosed over a year ago. No blockage, measured 13mm. My main issue is migraines. Migraines that will put me to the floor and feel like my head is going to explode. I turn bright red, veins buldge, eyes bloodshot, and have to lay down immediately. I feel I may pass out one day. My other issue is that I have cystic fibrosis, with that comes coughing. Coughing is not a friend of Chiari :( I went to the neurosurgeon and he stated that he wanted to do surgery. I did not want surgery as I have a 3 year old and a military hubby. He refused to do any other treatment as surgery was the only option. I should probably get a second opinion but I can't seem to find anyone who deals with Chiari specifically. Recently my neck and shoulders are starting to get very weak and I have severe lock jaw (not sure if that's related) as well as the feeling that my ears ring and are full of fluid. ENT says I have no issues. I just can't get any relief.
