Deafness, ear ringing, lying down is good. What's the reason?

Deafness and tinnitus lying down may be caused by physical weakness, or may be caused by frequent noise stimulation, dilation of small blood vessels in the ear and vascular malformation. In addition, hypertension, hypotension, autonomic nerve disorder and lack of blood supply to the brain may also cause symptoms of deafness and tinnitus lying down.
