First of all let me explain you that a given medical symptom like yours could be due to various causes. Back pain
and current like sensation could be due to spondylosis
in the cervical spinal cord
, or other causes (any tumor, demyelination
, spinal cord problem) can cause similar symptoms. In old age this could be due to spondylosis. You need a detailed neurological examination in order to determine the exact neurological problem. The presence of current like sensation is a point of concern as it suggests that one structure in the spinal cord is being compressed. Hence an urgent neurological evaluation will be required followed later by a repeat imaging and nerve conduction study
(may be optional depending upon the early evaluation). Your treatment will largely depend upon the cause. Hope this explanation will help you.
