Enhanced therapies for treating pain are described. The therapies include
subcutaneous stimulation of tissue in proximity to a source of pain at
low frequencies (less than about 20 Hz) and high frequencies (greater
than about 50 Hz). The subcutaneous stimulation may be applied in
proximity to a structure in the back, such as discs, facet joints, nerve
roots or ganglions, sympathetic chain, ligaments, muscles, and the like.
Subcutaneous stimulation at high and low frequencies applied in
combination with epidural stimulation is also described.
