Nummular headache: Subcutaneous peripheral nerve field stimulation as an individual therapeutic attempt

Abstract

Background: Subcutaneous peripheral nerve field stimulation (sPNFS) is an established procedure for the treatment of chronic localized neuropathic pain of peripheral origin. The treatment of nummular headache primarily focuses on conservative methods with limited prospects of success. The role of sPNFS in the treatment of nummular headache has not been investigated as yet. Question: Is the sPNFS an option in the management of nummular headache? Materials and methods: In addition to a summary of established methods in the treatment of nummular headache, sPNFS as a possible form of therapy is discussed. Results: A positive effect of sPNFS in terms of the treatment of nummular headache is shown. Discussion: sPNFS stimulates free subcutaneous nerves and transmits a pleasant form of paraesthesia in the area of pain. If regular conservative therapy has already been exhausted, then sPNFS might be an effective new option in the treatment of nummular headache. sPNFS is a minimally invasive and low-risk procedure. However, the high treatment cost and restrictions regarding fitness to undergo MRI are points of criticism. Further studies are needed to define its potential and role in the treatment of nummular headache.
