Pain levels for menstrual cramps and childbirth are graded according to the positioning of people’s experience. Clinical pain grading is developed by the World Health Organization to assess the pain level of the condition according to pain grading for menstrual cramps and childbirth, including pain reactions from injuries and stimuli. The grading is divided into 0-IV degrees, with 0 degrees indicating no pain. Degree I indicates mild pain, manifesting as paroxysms with periods of relief, and dysmenorrhea can mostly be relieved on its own without the need for medication; this grade is more common. Grade Ⅱ is moderate pain, the pain is persistent, without intermittent, like cramps, affecting rest and daily life, and can be relieved by painkillers. Grade III is severe pain, although it is also continuous, it is more intense than grade II pain and cannot be relieved without medication. Grade IV is severe and intense pain, so much so that blood pressure, heart rate and breathing are affected and changed, and the pain basically does not appear in menstrual cramps.
