Low back pain is a situation that many women encounter in their daily lives, and because the causes of pain are different for each person, the degree of pain and the manner in which low back pain occurs are also different. The main reasons are as follows: 1, lumbar muscle strain: long-term standing work of people, due to continuous standing, the lumbar tendons, ligament stretching ability is weakened, the local can accumulate too much lactic acid, inhibit the normal metabolism of the lumbar muscle, resulting in lumbar muscle strain and cause lumbago. 2, lumbar spine lesions: mostly seen in older women, with age, the symptoms of lumbar spine nerve compression will also increase. Pseudospinal column slippage caused by degenerative lesions is a more common lesion that can easily cause lumbar spinal stenosis, compressing the spinal cord and nerve roots, leading to lumbar pain and lower limb radiating pain. 3, urinary tract infection: because the female urethra is short and straight, and the urethra is close to the anus, there are often E. coli bacteria parasites, coupled with the characteristics of female physiology, the urethral orifice pollution opportunities, if you ignore hygiene, it is easy to occur urinary tract infection, causing back pain. 4, cold, trauma: women suffering from rheumatism, rheumatoid arthritis, mostly due to menstruation, childbirth and postpartum by wind, moisture, cold attack, resulting in spinal spurs and induced lumbago. 5. Reproductive organ diseases: Women’s reproductive organs have to undergo menstruation about four hundred times in their lifetime, and are also burdened with the missions of pregnancy and childbirth; some women also experience abortion and birth control surgery. Therefore, the incidence of inflammatory diseases of reproductive organs is higher, such as tubal inflammation and pelvic inflammatory disease. These inflammatory diseases are easily complicated by low back pain. Posterior tilt and retroflexion of the uterus is also one of the causes of low back pain in women, and serious reproductive organ disorders such as uterine fibroids, cervical cancer, ovarian cysts, etc. can cause compressive implication low back pain. 6, pregnancy and puerperium strain: during pregnancy, as the fetus grows, the lumbosacral and pelvic joints ligaments of pregnant women relax, while the weight of the uterus increases with the growth of fetal age, resulting in the forward shift of the body’s center of gravity. In order to maintain body balance, the waist more forward, if not pay attention to rest, it is easy to cause back pain. 7, other: duodenal ulcer is located in the right upper abdomen, when the ulcer is located in the posterior wall, it can be manifested as low back pain. In addition, menopausal women may also cause low back pain due to plant nerve dysfunction, which is characterized by morning lifting and reduced after activity.
