Notalgia paresthetica

Notalgia paresthetica (NP) is a medical condition characterized by chronic itching, usually on the upper back. The term "notalgia paresthetica" comes from the Greek words "notos" (back) and "algos" (pain), and the Latin word "paresthetica" (abnormal sensation).

Symptoms

The primary symptom of notalgia paresthetica is chronic itching, typically on a small patch on the upper back, usually on the left hand side. Other symptoms may include pain, tingling, numbness, or atrophy of the skin in the affected area.

Causes

The exact cause of notalgia paresthetica is unknown, but it is believed to be due to a problem with the nerve cells that provide sensation to the skin of the upper back (sensory neuropathy). Some researchers believe that it may be caused by a degenerative condition of the vertebrae or spinal muscles, or by a nerve impingement in the spine.

Diagnosis

Diagnosis of notalgia paresthetica is typically based on the patient's symptoms and medical history. A physical examination may reveal a hyperpigmented or hypopigmented patch on the upper back. In some cases, a skin biopsy may be performed to rule out other conditions.

Treatment

Treatment for notalgia paresthetica is primarily aimed at relieving the symptoms. This may include the use of topical creams or ointments, oral medications, or physical therapy. In some cases, nerve blocks or injections may be used.
