Excessive postoperative pain occurs after Spinal Cord Stimulator placement surgery due to muscle trauma and necrosis (death of muscles). During Spinal Cord Stimulator placement surgery, the muscles are torn off the spine by the surgeon in order to get down to the lamina. The permanently damaged muscles cause severe postoperative pain that requires opioid painkillers and muscle relaxers. Opioid painkillers are highly addicting, can cause tolerance, abuse and even death from breathing failure.
