Between each pair of vertebrae, spinal nerves branch off of the spinal cord and carry information to and from specific parts of the body. [32] The location of injury to the spinal cord maps to the body, and the area of skin innervated by a specific spinal nerve is called a dermatome.

Common infectious causes of back pain include osteomyelitis, septic discitis, paraspinal abscess and epidural abscess. [19] Infectious causes that lead to back pain involve various structures surrounding the spine. [27] Osteomyelitis is the bacterial infection of the bone.
