Girl’s stomach pain may be the following situations: first, because of gynecological inflammation, such as common cervicitis, endometritis, pelvic inflammatory disease, vaginitis, ovarian inflammation or salpingitis, etc. These common gynecological inflammation can often lead to increased permeability of the skin mucous membranes and blood vessels, and also lead to damage to the nerves or blood vessels, which can lead to stomach pain. Secondly, there may be tumors, such as common hemangioma, abdominal aneurysm, or endometrioma, pelvic tumor, ovarian tumor and uterine mucinous tumor, etc. When a girl suffers from these gynecological tumors, it can also lead to stomach pain. Thirdly, it may be due to having digestive system diseases, such as common gastric ulcer, intestinal ulcer, or chronic gastritis, superficial gastritis, enteritis, etc. These inflammatory diseases can also lead to stomach pain in girls.
