<s>[INST] I have numbness and tingling in my fingers for about two weeks, I also have sharp teasing pain on and of my right wrist, arm, shoulder and right to neck, I just felt 10000 volts electric current in my right arm that shook my whole body and I stood still for two minutes. please advise [/INST] Hi, Thanks for writing in. The nerves supplying the arms, wrist and hand originated at the cervical portion of spinal cord in the neck region. These pass through small foramen in the cervical spine and then reach the arm, wrist and hands. Sudden pinching of the nerve at its origin or anywhere along its route can cause numbness, tingling, pain or a sensation of current passing as described by you. If it has happened only on one occasion then there is no need to get worried. IF it happens regularly then you need to consult a neurologist and get examined in detail. This can also be a partial complex seizure and this requires complete clinical examination, electroencephalography and imaging scans. </s>
