Hello,
Cervical spondolysis or compression of the nerves can be responsible for the headaches and shock like sensations on moving the head.Just check out your posture and avoid taking a high pillow while sleeping.Regarding the numbness feeling ,it can be due to diabetes, hypothyroidism, and hypoparathyroidismThey can also be due to peripheral vascular disease, vitamin B12 deficiency or malnutrition.
Get your blood sugar and thyroid hormones levels evaluated. You can take some vit B12 for some days and see if the numbness is gone or not.
In case the symptoms persist then pls consult a neurologist as it can be due to some neurological disorder. Common disorders causing such symptoms are transient ischemic attack, motor neurone disease, or autoimmune disorders like multiple sclerosis or lupus erythematosus. A diagnostic evaluation by a doctor is necessary to rule these out.
Treatment will depend on the diagnosis.
Hope it helps.Take care and pls do keep me posted if you have any additional queries.Kind regards.
are you stressed at all? it could possibly be simple anxiety attacks or panic attack. I have had similar symptoms before for weeks at a time and they prescribed me ativan which worked well.
have you seen a doctor?
