The common causes of inguinal pain in pregnant women with inguinal pain are combined inguinal hernia, septic inflammation, lymphadenitis and other conditions, as follows: I. Combined inguinal hernia: If a female patient has a combined inguinal hernia, this condition can cause the intestinal tube and omentum in the abdominal cavity to protrude outward through the inguinal region, thus causing traction pain due to local impaction. In some patients, even if there is no impaction, the high intra-abdominal pressure can cause painful involvement of the intestinal contents, which can be avoided by applying pressure to the hernia belt to avoid the painful symptoms caused by repeated protrusion of the inguinal hernia. If the patient has an inguinal hernia with intussusception, causing ischemic necrosis of the intestinal canal, emergency surgery is required if necessary. Purulent inflammation: Some female patients may suffer from pain due to local inflammation of the inguinal area with hair follicles because of more sweating, which may cause purulent inflammation, and the local pain can be reduced by keeping the local skin dry and disinfecting it with appropriate external iodophor to control the local inflammation of hair follicles. Lymphadenitis: the pathogenic bacteria invade the groin area of pregnant women, where the lymph nodes have an inflammatory reaction, and the patient has painful symptoms. Patients can take antibacterial drugs for treatment under the guidance of a doctor.
