1. A method for treating a patient with chronic pain, the method comprising:
providing signals to at least one lead implanted in a patient, the signals based on sets of stimulation parameters, the lead delivering the signals to nerves and tissue of the dorsolateral spinal cord of the patient;
continuously monitoring patient parameters by recording sets of physiological measures from the patient;
fusing a set of physiological measures by categorizing each set of physiological measures as one of a plurality of discrete discomfort levels produced by the chronic pain, wherein a discomfort level may include lack of pain;
receiving sets of stimulation parameters selected by the patient;
recording which sets of stimulation parameters are selected by the patient for each discomfort level;
creating a table associating discomfort levels and selected sets of parameters; and
automatically providing signals to the at least one lead based on the table,
wherein the stimulation parameters consist of one or more parameters selected from the group consisting of: contact polarity, signal amplitude, pulse width, and frequency.
