High grade osseous neural foraminal stenosis with cervical spondylosis mean?

Pinched nerve: Cervical spondylosis is arthritis in the neck. Foraminal stenosis means narrowing of the space where the nerves exit the spinal canal, in this case caused by bone spurs from arthritis. After they leave the neck these nerves form the three major nerves of the arm, controlling feeling and movement. Stenosis can cause pain, weakness, numbness or tingling in the arm or hand. High grade = severe.
