Pelvic pain is a general term used to describe pain in the lower abdomen. The pain may be sharp and localized, or it may be dull and diffuse. It may be constant, or it may come and go. Pelvic pain can be caused by a variety of conditions, ranging from benign to serious. Common causes of pelvic pain include menstruation, ovulation, endometriosis, and Pelvic inflammatory disease. Less common causes include urinary tract infections, ovarian cysts, and tumors. If you are experiencing pelvic pain, it is important to see your doctor to determine the cause. In many cases, the cause can be treated successfully with medication or surgery. However, if the cause is unknown or cannot be treated effectively, chronic pelvic pain can be a debilitating condition.
