Others refer to the condition as lower abdominal pain, perineal pain, and sometimes genital pain. There are different causes of groin pain. Some groin pains are caused by sports related injuries such as football, soccer, ice hockey, and other sports activities that require a lot of footwork, There are also cases in which the groin pain is a symptom of the development of certain medical conditions such as development of kidney stone, appendicitis, some types of hernia, enlargement of lymph glands or the growth of a tumor.
