Hip bone pain in mid-pregnancy is mainly seen in the following two cases: 1. Because of the lack of exercise, long time sitting and bed rest, the sacrococcygeal area is in contact with the stool or bed, sometimes because the stool surface is too hard, or the bed board is too hard, resulting in inflammation of the sacrococcygeal fascia and muscle strain, this pain is generally based on soreness, swelling and stabbing pain, the pain point is relatively fixed, and the pain may be induced when bending over and moving around, and when lying prone The pain may be relieved when bending. The main treatment for this pain is to strengthen physical exercise, which can be combined with local ointment or topical rubbing of some Fotarine ointment. Another condition is that the intra-abdominal pressure increases after pregnancy, which leads to the aggravation of the already diseased disc herniation and the compression of nerves, resulting in lumbosacral neuralgia, which is mainly stabbing pain, and the pain is usually more intense and requires bed rest to relieve the symptoms.
