So I have been having awful head pain and migraines. Then I started missing my vision, having blury vision, loss of balance, concentration issues, memory issues, ringing of the ears, and more. I had chiari noted an an MRI but the neurons said it wasn't causing the issues. I went to the Wisconsin chiari center and the did a lot of testing including checking the flow. They said I definitely have chiari but my flow is fine. They said the overcrowding was causing the symptoms and that surgery could reduce symptoms but I would still have migraines. My question is I thought the flow was what caused the symptoms. Could it just be an over crowding issue? Thanks.
