Ive seen him sveral times over last 5 years. Both MRIs showed I had Arnold Chiari Malformation. I had medical symptoms that coincided with chiari and he kept telling me that it wasnt from the Chiari. Second MRI showed I had a syrinx and blood clot tumor. He still stated that was not causing my problems. Luckily I opted to do the decompression surgery 7 months later. My surgeon did an MRI, and I was 1.5 times worse. I now have permanent nerve damage and suffer chronic pain. Dont trust this doctor.
