Overview
Mittelschmerz is one-sided, lower abdominal pain that occurs in women at or around the time of an egg is released from the ovaries (ovulation).

What are the symptoms of Mittelschmerz?

 * Mittelschmerz may be felt on one side one month, then switch to the opposite side the next month, or it may be felt on the same side for several months in succession.


 * Symptoms include lower-abdominal pain that is:
 * One-sided
 * Typically lasting minutes to a few hours, possibly as long as 24-48 hours
 * Usually sharp, cramping, distinctive pain
 * Severe (rare)
 * May switch sides from month to month or from one episode to another
 * Begins midway through the menstrual cycle

What causes Mittelschmerz?

 * About 1 in 5 women have mittelschmerz, or pain associated with ovulation. The pain may occur just before, during, or after ovulation.


 * There are several explanations for the cause of this pain.
 * Just prior to ovulation: follicle growth may stretch the surface of the ovary, causing pain.
 * At the time of ovulation: fluid or blood is released from the ruptured egg follicle and may cause irritation of the abdominal lining.

When to seek urgent medical care?
Call for an appointment with your health care provider if ovulation pain seems to change, lasts longer than usual, or occurs with vaginal bleeding.

Diagnosis

 * A pelvic examination shows no problems.
 * Other tests (such as an abdominal ultrasound or transvaginal pelvic ultrasound) may be done to look for other causes of ovarian or pelvic pain, if the pain lasts a while.

Treatment options

 * No treatment is usually necessary.
 * Pain relievers (analgesics) may be needed in cases of prolonged or intense pain.
