SCS and DRG stimulation are both minimally invasive procedures that use a small implanted device to deliver electrical impulses to the nerves that transmit pain signals. SCS is typically used to treat chronic pain in the back, arms, or legs, while DRG stimulation is typically used to treat chronic pain in the lower body, such as in the hips, legs, and feet.

The devices used in SCS and DRG stimulation are similar to pacemakers and are implanted under the skin. A small wire is inserted near the nerves that transmit pain signals, and the device sends electrical impulses to the wire, interrupting the pain signals and replacing them with a tingling or buzzing sensation.
