[Painful legs and moving toes syndrome].

Painful legs and moving toes syndrome is a rare medical picture characterized by involuntary movements of the toes or the whole foot and pain in lower limbs. However, this must be kept in mind due to its association with other diseases and its possibility of being the first symptom. Spinal cord and cauda equina diseases, neuropathies, radiculopathies, drugs and other systemic diseases are the main cause of this syndrome although many cases are still idiopathic. Its diagnosis is essentially clinical and its treatment is complex, including different combinations of drugs and invasive techniques, and generally with a bad response.
