Headaches arise from pain receptors in the meninges and surrounding cranial structures
Headaches are well-documented to arise from the activation of pain receptors and nociceptive nerve endings located within the meninges and surrounding cranial structures.
The retrieved literature consistently supports the fundamental neuroanatomical and pathophysiological consensus that primary and secondary headaches (such as migraines and post-dural puncture headaches) are driven by the activation of nociceptors and pain-sensitive structures within the meninges and cranium.

The paper notes that meningeal nociceptive nerve fiber terminals express P2X3 receptors that mediate headache pain mechanisms.

The meninges are densely innervated by nociceptive sensory neurons that mediate pain and headache.
