What is the long term outlook (prognosis) for menstrual cramps?
In general, a woman’s menstrual cramps do not worsen during her lifetime. In fact, the menstrual cramps of primary dysmenorrhea usually diminish with age and pregnancy. This is thought to be due to the fact that the nerves of the uterus degenerate with age and disappear late in pregnancy, with only a portion of these nerves regenerating after childbirth.
