|Spinal Cord Stimulation (SCS) therapy has been adopted as a standard treatment modality for various chronic pain conditions. While the exact mechanism of action of this therapy is unknown, many theories have been postulated including: activation of gate control mechanisms, conductance blockade of the spinothalamic tracts, activation of supraspinal mechanisms, blockade of supraspinal sympathetic mechanisms, and activation or release of putative neuromodulators. The complication of SCS therapy includes lead migration, infection, pain at the battery site and device mechanical failure. There is no literature report of new onset pain after SCS lead insertion. Here we report five patients (six cases) of transient neuropathic pain, a previously unreported complication after SCS lead insertion.
