In most cases, cervical erosion does not cause pain. However, cervical erosion caused by inflammation of the cervix and vagina can result in lower abdominal pain in some patients. The primary reason for this pain is the irritation from the inflammation, which can lead to lower abdominal pain and discomfort in the lower back. Therefore, if a patient experiences pain in the lower abdomen and lower back, it is recommended to visit the gynecology department of the local hospital for a gynecological examination to determine whether there is cervical erosion and chronic inflammation, and to provide timely treatment if necessary.
