Could Scalp Pain Be a Type of Unclassified Headache?

The document discusses the phenomenon of scalp pain, which is often caused by infestations, infections, or inflammatory diseases. This type of pain lacks well-defined clinical characteristics and is not currently included in the ICHD-3 diagnostic criteria for headaches. The authors propose that scalp pain should be classified as a headache attributed to a scalp disorder in future headache classifications.
