What can i do about pins, needles, and numbness after a chiari operation and cervical discectomy?

Further workup: Your options depend on the location of the pins/needles sensation, your symptoms before your chiari surgery, the severity of the chiari, and the operation on your cervical spine. You should start with your family md for an evaluation and they can do a workup. You could then be referred to a neurologist or neurosurgeon for examination and discussion of your findings/options.

Get an image: Symptoms are suggestive of residual cervical canal and/or neuroforaminal stenosis, or pressure upon the cord such as buildup of cerebrospinal fluid e.g. Formation of a pseudomeningocele. An MRI of the cervical spine will show any significant problem.
