Labor pain experience is highly individualized and will depend on a woman's emotional, motivational, cognitive, cultural and social circumstances.
There is no other circumstance where it is considered acceptable for a patient to experience severe pain that is amenable to safe intervention while under a physician's care.
The pain felt during the 1st stage of labor originates from the rhythmic contractions of the lower uterine segment and progressive cervical dilation mediated via T10-L1 spinal nerves.
The pain in the 2nd stage of labor is more intense due to stretching of the vagina, vulva and perineum as the fetus descends in the birth canal superimposed by the pain of uterine contractions, and is transmitted through the S2-S4 spinal segments.

Dysmenorrhoea is a medical condition characterized by severe uterine pain during menstruation manifesting as cyclical lower abdominal or pelvic pain, which may also radiate to the back and thighs. The term dysmenorrhoea is derived from the Greek words ‘dys’ meaning difficult, painful or abnormal, ‘meno’ meaning month, and ‘rrhea’ meaning flow. It is commonly divided into primary dysmenorrhoea, where there is no coexistent pathology, and secondary dysmenorrhoea where there is an identifiable pathological condition known to contribute to painful menstruation. Symptoms of primary dysmenorrhoea begin a few hours before the start of menstruation and are often relieved during the first few days of bleeding. The initial onset of primary dysmenorrhoea is usually shortly after menarche (6–12 months), when ovulatory cycles are established. Secondary dysmenorrhoea can also occur at any time after menarche but is most commonly observed in women in their third and fourth decade of life in association with an existing condition.
Adolescent females often experience menstrual problems, and these are usually related to mood changes. In this study, the association between dysmenorrhea and depressive symptoms, anxiety, and premenstrual syndrome was examined.
