Discogenic pain in the neck can occur through trauma or may develop gradually over time. The cervical discs are fibrous in most adults so the disc does not commonly bulge but rather becomes damaged with circumfrential tears in the annulus or outer fibres of the disc progressing to radial tears. A common feature with discogenic pain is limitation in flexion and extension as the disc is compressed to a greater extent in these positions. Discogenic pain can also produce pain called clowards signs in the region of the shoulder blade .
