Spinal Cord Stimulation (SCS) is a procedure that helps manage chronic pain by sending electrical signals to the spinal cord. These signals interfere with pain messages before they reach the brain, which can reduce the feeling of pain. The procedure is often considered when other treatments, like medications or physical therapy, have not provided adequate relief.

During SCS, a small device, similar to a pacemaker, is placed under the skin. Thin wires also called leads are inserted near the spinal cord. The device sends mild electrical pulses through the electrodes to the spinal cord. This procedure is done percutaneously, which means it's minimally invasive and involves small incisions.

Patients often feel a tingling sensation in the area where they usually experience pain, which helps to lessen the pain. It's commonly used for conditions like failed back surgery syndrome, complex regional pain syndrome, or other long-lasting nerve pain.

While this treatment can greatly improve quality of life, there are alternatives to consider like medication management, physical therapy, or, in more severe cases, further surgery. Risks include infection, bleeding, or lead movement, which may require additional adjustment or surgery. Most people resume light activities soon after and may gradually return to normal activities as guided by their doctor. Trial stimulation is usually conducted to ensure SCS will be effective for each patient before a full implant.
