Shoulder area numb: The lack of CSF flow around the chiari area is thought to raise the risk for a fluid collection inside the cervical spine called a syrinx. This can cause arm/hand symptoms with some numbness in a shawl pattern across the shoulder area. An MRI through your cervical spine should show this fluid collection if it is there. It can be followed after the chiari is decompressed usually resolving by itself.
