Introduction
Pain in the lower bones during late pregnancy is generally caused by compression of the sciatic nerve, pubic symphysis separation, and fetal head engagement. In addition, it could also be due to inflammatory conditions such as vaginitis or pelvic inflammatory disease. Pregnant women are advised to pay attention to postpartum recovery, ensure adequate rest, balance work and relaxation, and avoid prolonged standing, which may otherwise lead to persistent pain in the lower bones.
Pain in the lower bones during late pregnancy may be caused by compression of the sciatic nerve, pubic symphysis separation, or fetal engagement. Pregnant women are advised to rest adequately and avoid prolonged standing, as this may lead to persistent bone pain.
1. Sciatic Nerve Compression
In late pregnancy, the fetus is mostly developed and increasingly occupies more space, gradually expanding the uterus and thereby compressing the pregnant woman's sciatic nerve, leading to pain in the lower bones. This condition is very common and normal. By resting properly and avoiding prolonged sitting or standing, symptoms can gradually improve.
2. Pubic Symphysis Separation
Pregnancy causes hormonal changes in the body. As the delivery date approaches, these hormones soften muscles and ligaments to facilitate the baby’s passage through the birth canal. Consequently, a pregnant woman's ligaments become more relaxed, which may result in pubic symphysis separation and cause bone pain.
3. Fetal Engagement
Pain in the lower back and groin area may also occur when the fetus descends into the pelvis. The baby pressing against the pelvic bones stretches surrounding muscles and tissues, causing discomfort. Typically, these symptoms ease after childbirth.
In addition, inflammatory conditions such as vaginitis or pelvic inflammatory disease may also cause bone pain. Pregnant women should pay attention to postpartum recovery and seek medical advice promptly if they experience any discomfort.
