No chiari. I think it is trama induced from a car accident in 92', and now it has become big enough to cause problems. I have to go for a cervical steroid injection in a week for degenerative disk impinging on the spinal cord and I am so scared. I hope it doesn't affect the syrinx. I definately like walking still, even if it slow and difficult. For 36, I feel 90.... So not fair, but thank you for your response. It helps when you find someone who makes you feel like you matter.
