It's cold. How is the ass ache?

The pain behind the buttocks during pregnancy is mainly caused by the oversized uterus and the weight of the fetus pressing the sciatic nerve. In addition, calcium deficiency during pregnancy can easily lead to hip pain, and sedentary will also oppress the sciatic nerve. (1) Changes in body weight. Because of pregnancy, you gain weight, your uterus gets bigger, and your fetus grows every week. At the same time, the decompression and relaxation of joints and ligaments weaken the stability of your waist and bring great pressure to the sciatic nerve. Excessive pressure can easily cause sciatica, buttock pain and lumbago and leg pain. (2) the change of posture. The weight of the fetus is concentrated in front of the body, so the burden on the waist increases. Being pregnant is like carrying a backpack in front. This change increases the burden on the waist and easily causes butt pain.
