Pain in the right crotch may be caused by acute appendicitis or by an inguinal hernia on the right side. The location of the pain should be determined. If the pain occurs in the right lower abdomen with pressure on the abdomen, it may be appendicitis, and routine blood tests and appendiceal ultrasonography are needed for further clarification; if the routine blood tests reveal elevated white blood cells, and the abdominal ultrasonography reveals swelling of the appendix with oozing around it or an embedded fecal stone in the appendiceal cavity, it is acute appendicitis, and surgery is recommended, that is, laparoscopic appendectomy. If the right inguinal hernia is embedded, it can also lead to pain in the right side of the hip, manifested by a mass in the right inguinal region, which cannot be retracted, and significant pain when pressing on the mass, which usually requires surgical treatment to loosen the embedded inguinal hernia and return the contents. If the embedded time is relatively short and there is no obvious bacterial contamination, a tension-free hernia repair can be performed in one stage.
