is acute or chronic pain that occurs because of a tumor, arthritis, or an hnp.

The correct answer is "radiculopathy".

This is described as acute or chronic pain associated with the nerve roots located in the spinal cord. A tumor compressing the nerve roots; arthritis wherein swelling also involves the nerve roots; or a herniated nucleus pulposus or HNP which compresses the nerve roots will produce radiculopathic pain.
