There are many causes of numbness and tingling along with electric shock like sensations. Some of them are- Zinc poisoning, Anxiety, Neuropathy and Sciatica. It could be a part of Complicated Migraine syndrome as well. Please go for an MRI of the brain and spine and wait for the neurologist appointment. If the symptoms are really bothering you, you may consult a physician to get primary investigations done to find out whether it is anxiety, zinc poisoning or part of Migraine syndrome. If one of these is the cause, you can start the treatment right away with the physician advice. Hope this helps you. Take care and regards!
