This review summarises aetiology, diagnostic approach, and treatment of longstanding groin pain, which can be divided in adductor-related, pubis-related, iliopsoas-related, and inguinal-related pain. Among the diagnoses included in the inguinal-related entity is the so-called sports hernia. However, the terminology is a misnomer since sports hernia is characterised by not being a hernia. Both athletes and non-athletes are affected, and the condition may cause long sick leaves. The treatment is primarily exercise treatment. If this treatment is unsuccessful after 2-6 months, surgery is an option.
