Somatosensory Outcomes Following Re-Surgery in Persistent Severe Pain After Groin Hernia Repair : A Prospective Observational Study
Purpose: After groin hernia repair (globally more than 20 million/year) 2–4% will develop persistent severe pain (PSPG). Pain management is challenging and may require multimodal interventions, including re-surgery. Quantitative somatosensory testing (QST) is an investigational psychophysiological tool with the potential to uncover the pathophysiological mechanisms behind the pain, ie, revealing n
