### output:

Hi, At this age there are few possibilities giving rise to this problem.1, Cerebrovascular insufficiency,2, Postural hypotension,3, Cervical spondylitis,4, Some problem in ear like Sclerosis. As you get pain at back of neck is again sign of cervical spondylitis. Vertigo, you feel also common in C. spondylitis. Go for S.cholesterol, Lipid profile. CT scan also will give some important clue about your problem. Consult Neuro-physician and discuss this. Ok and take care.
