Chronic central neuropathic pain associated with multiple sclerosis – http://id.who.int/icd/entity/2044099972

Chronic central neuropathic pain in multiple sclerosis is caused by a lesion of somatosensory brain regions or their connecting pathways. The pain may be spontaneous or evoked, as an increased response to a painful stimulus (hyperalgesia) or a painful response to a normally nonpainful stimulus (allodynia). The diagnosis requires a history of multiple sclerosis and a neuroanatomically plausible distribution of the pain. Negative (e.g., decreased or loss of sensation) or positive sensory symptoms or signs (e.g., allodynia or hyperalgesia) indicating the involvement of the brain or spinal cord must be present in the area of the body affected by pain.
