title: Recurrent limb pain and migraine: case reports and a clinical review.
abstract: Recurrent limb pain (RLP) is a well-known entity in childhood. It is considered a precursor of migraine. The temporal relationship of RLP with headache in childhood is lacking in the literature. However, there are many cases with limb pain in a close temporal relationship with migraine headache in adults. We report six female patients with RLP and migraine and delineate the temporal relationship between the two. Three patients had a history of RLP in childhood and developed migraine headache after many years. Conversely, two patients had a long history of migraine headache and later developed RLP. One patient developed RLP and migraine headache at the same age. Isolated limb pain was frequent in all six patients. It was mild to severe, for a few minutes to a few days, and predominantly located in the upper extremities. Only one patient reported allodynia. The patients showed response to preventive measures (all six patients) and abortive therapies (four patients), even in those attacks of RLP that were not associated with headache episodes. We also review the clinical profiles of the patients in whom RLP and migraine were related to each other, and speculate on the possible mechanisms for RLP in the patients with migraine.
