The history of the use of electrical stimulation for pain is a cavalcade of research and innovation of many great scholars, scientists, and physicians over centuries that continues up to the present day. The legacy of this philosophy, research, and innovation is the field of neuromodulation for pain control. Today, patients with chronic pain from damage to the nervous system and chronic pain of the extremities, the axial low back, and neck, the face, and the viscera, all derive benefit from these early pioneers that have led to the expanding field of neuromodulation ... "on the shoulders of giants." We present here a history of the understandings of pain from the ancients to the present, which has led to our understandings of the use of electricity to cure disease and release patients from their suffering, generating the new, exciting, and expanding field of neuromodulation.

Complications of intrathecal drug delivery are relatively rare. Of these, infections, cutaneous erosion, and granulomas account for the most common complications. The latter is often noticed when the patient shows signs of sedation and/or reduced pain relief. ⋯ Here, we present a case where a catheter-tip granuloma formed within 5 weeks of intrathecal morphine. The patient was carrying an intrathecal pump for 3 months when it was diagnosed. Probable causes of the formation are discussed.

Currently accepted chronic pain treatment algorithms have positioned therapies according to levels of invasiveness and up-front costs. After reviewing updated literature on efficacy and cost outcomes of care for patients with chronic pain that include interventional implantable technologies, we offer a new model of thinking when formulating algorithms of care that might include more invasive and costly interventions such as spinal cord stimulation, the SAFE principles. These SAFE principles include "safety,"appropriateness,"fiscal neutrality," and "efficacy."
