Soreness in the hips after pregnancy is relatively common, especially in the middle and late stages of pregnancy when the fetus is larger and the pressure of the uterus on the surrounding organs and blood vessels is more pronounced, therefore it may affect the blood circulation in the hips and lead to a sore feeling. In addition, after pregnancy, due to the presence of the foetus, pregnant women have more nutritional needs and if they cannot meet their normal requirements and suffer from calcium deficiency, this may lead to osteoporosis, which can easily lead to soreness and painful sensations.
