The World Health Organization classifies pain into 0-IV pain, and the pain of childbirth belongs to II-III pain. 1.0 degree: no pain; 2.I degree: mild pain, intermittent pain, no medication; 3.II degree: moderate pain, continuous pain, affect rest, need to use painkillers; 4.III degree: severe pain, continuous pain, no medication can not relieve the pain; 5.IV degree: severe pain, continuous severe pain with changes in blood pressure, pulse, etc. Many people rumor that the pain is 10 or 12, this is not the standard pain classification. It is true that childbirth is very painful, so some people exaggerate its level. Pain during labor varies greatly from person to person, with people in different pain ranges, those in the lower range can be very painful, and those in the higher range can get through labor. After all, contractions are not always painful, but at intervals, so don’t be overly stressed. Pain is a subjective feeling, and everyone has different degrees of pain perception. The same uterine contractions are observed clinically with different feelings. Everyone’s sensitivity to pain, ability to tolerate it, and the terms used to describe it are different, so don’t overly obsess about it before giving birth, and make sure to relax and face it correctly.
