    AbstractDorsal column (dcSCS) and dorsal root ganglion stimulation (DRG-S) complications are similar, typically related to placement and device failure. We present the first case of tinnitus after DRG-S implantation. The patient presented with complex regional pain syndrome (CRPS) type 2. After previous failed treatments, she had a lumbosacral DRG-S trial, which provided relief; however, she briefly noted ringing in her ears. After permanent implantation, she reported persistent, intolerable left-sided tinnitus. Tinnitus can be modulated by secondary somatosensory inputs to the cochlear nucleus from the dcSCS. Therefore, lumbosacral DRG-S stimulating distal sensory neurons leading to tinnitus is a feasible complication.Copyright © 2024 International Anesthesia Research Society.
