Persistent sensory dysfunction in pain‐free herniotomy

Background: Persistent post‐herniotomy pain may be a neuropathic pain state based on the finding of a persistent sensory dysfunction. However, detailed information on the normal distribution of sensory function in pain‐free post‐herniotomy patients hinders identification of exact pathogenic mechanisms. Therefore, we aimed to establish normative data on sensory function in pain‐free patients >1 year after a groin herniotomy.
