Abdominal paresthesia resembling restless legs syndrome successfully treated with iron supplement therapy: a case report.

Restless legs syndrome (RLS) is a sensorimotor disorder characterized by the urge to move or an unpleasant sensation in the legs. Recently, some cases in which paresthesias with the urge to move body parts other than the legs have been reported [ 1 Fukunishi I. Kitaoka T. Shirai T. Kino K.

These cases have been assumed to be phenotypic variants of RLS and successfully improved with dopaminergic medications, the most common treatment choice for RLS. Here, we report the first case with abdominal paresthesia resembling RLS, which was successfully treated with iron supplement therapy.
