As the fetus grows in late pregnancy, the uterus gradually increases in size, which can cause compression symptoms on the lumbar spine and pelvis. Symptoms such as tailbone pain, pubic bone pain, and lumbar pain appear. To relieve pain, you can choose hot towels and hot water bags for hot compresses, physical therapy and massage to relieve symptoms. Avoid bending and carrying heavy objects during late pregnancy, and do not stand or sit for a long time, and move your limbs appropriately or practice yoga to relieve discomfort. In late pregnancy, with the needs of fetal growth and development, it is recommended to take appropriate calcium supplements, sunshine and drink more milk to promote calcium absorption. You can also use a pregnant woman’s pelvic bag to hold the abdomen and relieve the pressure to relieve the pain. Pay attention to rest, pay attention to a light diet and balanced nutrition.
