Low back pain during the menstrual period does not necessarily lead to a disease. Most women’s back pain symptoms will disappear between 3-6 months after delivery, but if the back pain symptoms last longer and get progressively worse, it is important to visit an orthopedic clinic in time. There are many causes of low back pain during menstruation, first of all, we should exclude organic lesions, lumbar muscle strain, lumbar disc bulge, bone injury, it may be due to long-term compression of the lumbosacral nerve by the enlarged uterus during pregnancy, which leads to low back pain, or it may be due to the consumption of a large amount of calcium in the body during pregnancy or puerperium, which is not supplemented with calcium in time, which leads to low back pain. In addition, cold stimulation, lumbar muscle strain, lumbar disc herniation, and urinary system diseases can cause low back pain. If low back pain occurs during the puerperium, you should go to the hospital as soon as possible for systematic examination and treatment after clarifying the specific cause. Most patients can be relieved or cured after treatment and good rest and recuperation, and usually no root of the disease will be left behind. Women during the menstrual period should develop good habits, do not be sedentary for a long time, exercise properly, pay attention to calcium supplements and keep warm. Avoid heavy physical labor and heavy physical work during the menstrual period.
