Notalgia paresthetica (NP) is a condition characterized mainly by unilateral pruritis in an area medial to the scapula and lateral to the thoracic spine.
Notalgia paresthetica, like DSN neuropathy, is predominantly a chronic condition found in middle to older aged women at a 2:1 or 3:1 ratio versus men.

Localized pruritus of the midback, called notalgia paresthetica
(NP), occurs in about 10% of the population.
After exiting the spinal column, the nerves make a 90-degree turn so they can go through the muscles to the skin of the back, which is "a unique course for a very short nerve" and may irritate that nerve, resulting in notalgia paresthetica. In a few studies, spinal arthroses and protruding disks have correlated with the symptoms, offering highly suggestive circumstantial evidence that notalgia paresthetica is sometimes associated with arthritis and other conditions that produce changes in the spinal column.
Radiographs suggest that, as with notalgia paresthetica, arthritic changes or disc protrusion correlate with the itchy area.
