Groin pain, or inguinodynia, can arise from a wide range of causes, including inguinal hernias, nerve entrapment, musculoskeletal injuries, chronic postsurgical pain, and numerous other etiologies, including gynecological, genitourinary, orthopedic, gastrointestinal, or psychological disorders. The evaluation and treatment of patients experiencing groin pain after inguinal hernia repair should follow a structured and algorithmic approach. The process should begin with a comprehensive history and thorough physical examination, including an assessment for recurrent hernias, targeted imaging studies, with consideration of its anatomical and technique-specific implications. This chapter will detail our comprehensive approach to diagnosis (following the “SPORT” sequence) and management of postoperative groin pain.
