What are the causes of coccyx pain in pregnant women?

Pregnant women will definitely feel pain in all aspects of their bodies during their daily lives. As their stomachs slowly swell, they will experience back pain, leg numbness, leg soreness, and calcium deficiency. Some pregnant women also experience pain in their coccyx. In fact, there is no need to panic. These are so-called common symptoms in life. Today we will share with you some of the reasons and what you should pay attention to!

The human pelvis is composed of the sacrum, coccyx and left and right hip bones (including ilium, pubis and ischium). At the back of the pelvis, the ear-shaped articular surfaces of the hip bones on both sides are connected to the articular surfaces of the sacrum on both sides, forming the sacroiliac joints. In the front, the left and right pubic bones embrace each other to form the front half of the pelvis. The two pubic bones are connected by a fibrous cartilage plate to form the pubic symphysis, which is surrounded by tough ligaments for protection, making the two pubic bones tightly combined together with a very small cavity that is not easy to move. It is estimated that the pubic symphysis is not likely to separate or dislocate even if it is subjected to a traction force of 328 kg.

However, when a woman becomes pregnant, things change. When the pregnancy is 7-10 weeks, the pregnant woman's ovaries secrete a substance called "relaxin", which gradually increases with the increase of pregnancy period. Relaxin can relax the fibrous cartilage and ligaments of the sacroiliac joints and pubic symphysis, and widen the pubic space to accommodate the growing fetus in the uterus. In the late pregnancy, the gap in the middle of the pubic symphysis may even widen to 0.3-0.4 cm to prepare for the smooth delivery of the fetal head during childbirth.

Most pregnant women will be safe and sound with the above-mentioned changes in the pubic symphysis. Only a few will experience local pain, which generally does not affect normal work and life. As long as they pay attention to avoid heavy physical labor and long-term walking, no treatment is required. Pulling pain will only occur when the pubic bones are separated too much, especially when walking or walking upstairs. Because the body's center of gravity is biased to one side, the pubic bones are dislocated, pulling the fibrous cartilage and ligaments between the pubic bones, which is more likely to cause pain. Those with severe symptoms may even suffer from ligament rupture and edema, making them unable to move.

The key to preventing pubic separation in pregnant women is prevention, which should be done as follows: actively participate in physical exercise to enhance muscle and ligament tension; pregnant women should not stay absolutely still during pregnancy, and may do some thigh flexion and extension exercises, but should avoid large movements of the waist and hips and other strenuous exercises; if a pelvic joint suffers from tuberculosis, rheumatism or softening, pregnancy should be resumed after recovery; nutrition during pregnancy should be moderate to prevent the fetus, especially the fetal head, from being too large and aggravating pubic separation during delivery.

At the same time, avoid chronic cough, constipation and other conditions to avoid further increasing abdominal pressure; heavy physical labor should be avoided in the middle and late stages of pregnancy, especially weight-bearing walking; the fetal head usually enters the pelvis 2 weeks before the due date of delivery, and after entering the pelvis, the pubic bone may further separate, so pregnant women who have the conditions can take a leave at home two weeks before delivery.

Coccygeal pain is very common among pregnant women. Usually, we just need to prevent it, take more calcium supplements and massage the thighs appropriately. During pregnancy, we can do activities in bed, and massage can effectively help the body resume activities as soon as possible.
