Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

What is notalgia paresthetica?

Notalgia paresthetica is a common chronic, localized itch, that usually affects patches of skin on the upper back. Occasionally be more widespread and involve other parts of the back, the shoulders and upper chest. People feel both the sensation of an itch and paresthesia (a sensation of tingling, pricking, or numbness of the skin).  There are no signs on the skin except for signs of chronic scratching and rubbing.  Amyloid deposits (a collection of a specific type of protein) may be found in skin biopsies, but this is thought to be a secondary event.  The cause of the itch in notalgia paresthetica may be due to the compression of spinal nerves by bones or muscles as the nerves emerge through the vertebrae to the back muscles.  Sometimes degenerative changes in the area of the vertebrae that innervate the affected back muscles can be seen, but not always.  Symptoms of notalgia paresthetica may respond to topical capsaicin treatment.[1][2]

Is notalgia paresthetica a hereditary condition?

After an extensive search of the resources available to us, we have found no indication that this condition is hereditary. While the exact cause of notalgia paresthetica remains unclear, it is widely believed to be a neurogenic itch resulting from spinal nerve impingement or chronic nerve trauma.[3][4][5][6]
