The causes of groin pain mainly include the following: the first cause, consider the pain caused by soft muscle soft tissue strain in the groin area. There are inguinal ligaments and other muscles and soft tissues in the inguinal region. The pain caused by this cause can be relieved significantly by resting and applying topical ointments to activate blood circulation and remove blood stasis. The second cause is considered to be pain caused by lymphadenitis in the inguinal region. If there are inguinal lymph nodes in the inguinal region, if the inguinal region is stimulated by local or systemic inflammation, the inflammation and enlargement of the inguinal lymph nodes will cause pain in the groin, and the pain will be accompanied by redness and swelling in the inguinal region. The third reason is that the pain is caused by inguinal hernia gaston. The inguinal region is a good site for hernia, and if the hernia is ingrown and cannot be retracted, it will also cause pain in the inguinal region, which can be clarified by ultrasound examination.
