Both size and shape of the painful area remain constant since the onset of symptoms. A 57-year-old woman presented with a history of focal episodic pain in a circumscribed area on the right parietal region. The administration of standard oral doses of palmitoylethanolamide and topiramate in combination showed an improvement in pain symptoms and on pain measuring scales.
