1. A method for treating one or more restless leg syndrome (RLS) symptoms of a patient, the method comprising:
generating first and second stimulation waveforms using a waveform generator;
electrically stimulating at least a portion of a sacral region of the patient, based on the first and second stimulation waveforms, using at least four electrodes; and
damping or interfering with electrical signals transmitted along the patient's femoral nerve to the patient's legs based on the electrical stimulation, wherein:
a first electrode is positioned on a left portion of the patient's lumbar region and configured to receive the first stimulation waveform on a first channel;
a second electrode is positioned on a right portion of the patient's lumbar region and configured to receive the second stimulation waveform on a second channel separate from the first channel;
a third electrode is positioned over a hamstring of the patient's right leg and configured to receive the first stimulation waveform on the first channel; and
a fourth electrode is positioned over a hamstring of the patient's left leg and configured to receive the second stimulation waveform on the second channel.
