Understanding New and Severe Abdominal Pain

It is very likely that your pain is caused by normal menstruation. The symptom of pain with menstruation is named "dysmenorrhea." Usually, nonsteroidal anti-inflammatory pain medicines such as ibuprofen are very helpful.

Another problem that can cause pain before or during menses is "endometriosis." Endometriosis occurs when endometrial tissue (tissue that is normally found lining the inside of the uterus) is present in the pelvis or abdomen outside of the uterus. Endometrial tissue can ooze blood at the time of your menses, wherever this tissue is located.
