I was diagnosed with Arnold-Chiari Malformation with a syrinx in Feb.2000. My symptoms worsened so I elected to have surgery in June of 2000. The surgery was successful to the neurosurgeons satisfaction. I am still very sick. I no longer have pressure headaches but I do have constant neck pain, back pain, my eyes hurt, and constant burning in my right shoulder, arm, and hands. If you know something that I don't please let me know. As I am concerned about your progress.
