What is the cause of burning numbness pain on the bone behind my right ear?

Organs of the body are attached to the spine and there are also nerve endings to contend with. You could have slept wrong (scrunched up on your pillow) tossed and turned all night without realizing it. If you sleep wrong or even slightly injure yourself at work or at home you could have injured a nerve or bruised the nerve causing the lack of blood flow. This is usually not serious, but if it continues for more than 3 weeks then you should see a specialist about it.
