Restless “lower back” in a patient with Parkinson’s disease
Background: In restless legs syndrome (RLS), the isolated involvement of other body parts in the absence of leg involvement is rare.
Case report: We report an 82‐year‐old male with a 1‐year history of Parkinson’s disease (PD) who developed an abnormal sensation limited to his “lower back.” He fulfilled the four essential RLS criteria, with the major caveat that the criteria were applied in a modified manner to his lower back rather than his legs. The administration of a dopamine agonist completely eliminated his symptoms.
Discussion: Our patient’s “restless lower back” may be a variant of RLS. Clinicians should pay attention to restlessness in other body parts in addition to the legs.
