If a woman’s belly button hurts inside, consider whether it is navel infection. If the belly button is inflamed, in addition to pain there will also be redness and swelling around the belly button and a painful sensation when pressed. If the pain is uncomfortable inside the navel, it may be caused by diet and other reasons, such as eating raw, cold, unhygienic and indigestible food, which causes intestinal spasms as well as enteritis. It may also be a more serious disease, including intestinal torsion, intestinal obstruction, acute pancreatitis, and other diseases of the digestive system. Female patients also consider gynecological inflammatory diseases, such as pelvic inflammatory disease and adnexitis, and possibly inflammatory diseases of the urinary tract, all of which are accompanied by other symptoms and require further examination at the hospital for a clear diagnosis.
