I am facing neck pain  and stiffness in my hand and legs  can't turn my head   and back pain and dizziness   for more than two months I visited Ortho and physio but no cure. And then visited neuro doctor he recommended Cervical MRI ,vitamin d25 and calcium test .he told  all are normal just some nutrient deficiency.but I can't bent and turn my head I feel floating sensation sometimes .

Whenever i bend down i feel a pressure in my head n i have to get up immediately.. otherwise also my head stays a bit heavy esp on right side.. sometimes i feel tired n weak to get up n walk around. I feel my brain not getting complete oxygen .. my blood tests, ecg, vitamins all okay... neuro advise MRI Brain to rule out serious issues- got it done today and Report available, but the neuro doctor will see it after two days, so can you check it and advise me something for my symptoms?

Whenever I go out somewhere or study too much I get severe headache. Along with the headache my head also spins, my head gets dizzy and my eyes also open
