The pelvis of the human body consists of the tibia, the tailbone and the left and right hip bones. The bone and bone of the pelvis are connected by the pubic symphysis in front of the pelvis and the posterior ankle joint, appendix joint and two pairs of tendon ligaments and sacrospinous ligaments. A pelvis that is tightly bound by a few bones acts like a bone. Women who are not yet pregnant, the pelvic joints are inactive, so there is no pain. And once a woman is around 10 weeks of gestation, the ovaries secrete a substance called "relaxin", which relaxes the soft cartilage and ligament of the ankle joint and pubic symphysis, and widens the joint of the ankle and pubic bone. Increased activity. By the end of pregnancy, the average pubic symphysis is 0.3-0.4 cm wide, and the appendix joint can be moved back up to 2 cm to facilitate the fetus passing through the bone birth canal during childbirth. However, if the ligament is excessively loose, the pubic symphysis will be separated. The humerus cannot fix the left and right humerus, and the pelvis lacks stability. When the pregnant woman walks, sits up, goes up and down the stairs, and turns over, the bones of the pelvis will move. Pulling the fibrous cartilage and ligament between the pubic bones, causing pain in the pubic and ankle joints. In severe cases, the pain may also radiate to the roots or the perineum of the thighs, and even cause difficulty for pregnant women to move.

Pelvic pain needs to be differentiated from the following symptoms:

Soreness caused by dense ankle arthritis: The reason for this backache is that due to endocrine function, the tendon ligament is loose, causing the ankle joint to loosen and lose stability. Therefore, the ankle joint is often subjected to abnormal irritation or damage. Some doctors believe that it is caused by ischemia and osteoporosis of the ankle joint during pregnancy. Pregnant mommy will feel pain in the lumbosacral region, sometimes radiating down to the buttocks and thighs on both sides.
