Nocturnal leg cramps. Clinically mysterious and painful--but manageable.
Nocturnal leg cramps are common occurrences among older, generally healthy adults. Although there are many known causes--endocrinologic, neurologic, and vascular disorders, treatment with certain drugs, and occupational factors--a significant portion of cases are idiopathic. History, physical exam, and laboratory testing can provide clues for distinguishing between cramps with identifiable causes and idiopathic cases. For nonidiopathic cases, management consists of treating the underlying cause whenever possible. A nonpharmacologic approach (massaging and stretching) is the recommended first-line treatment for idiopathic cases. Quinine sulfate also appears to offer safe and effective symptom management of idiopathic cases, although its efficacy has not been definitively established in clinical trials.
