Low back pain is a symptom of pain in the middle of the lumbar pelvic area and/or one (bilateral) side of the vertebrae, which occurs in both men and women, with women being the majority. Common causes are mainly the following: a. lumbar muscle strain, ligament inflammation or small joint disorders: people who bend or sit for a long time, due to continuous bending, lumbar muscles and ligament stretching ability is weakened, the local can accumulate too much lactic acid, inhibit the normal metabolism of the lumbar muscle, can lead to lumbar muscle strain and caused by lumbar pain; often carry heavy objects or sports injuries, lumbar overload, prone to spinal scoliosis, resulting in lumbar muscle sprain and Low back pain occurs. Common diseases include: lumbar myofasciitis, supraspinous ligamentitis, interspinous ligamentitis, sacroiliac arthritis, third lumbar transverse synovial syndrome, etc. Connective tissue disease or rheumatic disease: due to autoimmune system problems, resulting in changes in the lumbosacral musculoskeletal system, such as ankylosing spondylitis. Rheumatic diseases are mostly attacked by wind, dampness and cold, which induce lumbago, mostly showing morning stiffness and waking up in the middle of the night with pain. Third, pregnancy and puerperium strain: during pregnancy, progesterone increases, so that the pregnant woman’s whole body ligaments relax, especially the lumbosacral and pelvic joints ligaments relax, while the weight of the uterus also increases with the growth of the gestational age, resulting in the body weight forward – in order to maintain body balance, the waist more forward, if not pay attention to rest, it is easy to cause lumbago; during pregnancy, fetal development requires sufficient calcium, phosphorus and other nutrients During pregnancy, the fetus needs sufficient calcium, phosphorus and other nutrients to develop, but if the dietary intake is insufficient, it can cause bone softening and decalcification in pregnant women, which can also cause low back pain; excessive bleeding during the puerperium, or too much labor too early, too tired and cold, etc. can also cause low back pain. This is the pregnancy-related low back pain or pregnancy-related pelvic girdle pain that is being increasingly emphasized. Fourth, degenerative lesions of the lumbar spine: Most often seen in the elderly, as they age, the symptoms of lumbar nerve compression increase. Bone redundancy formation, thickening of the ligamentum flavum and pseudospinal slippage caused by degenerative lesions are more common lesions, which can easily cause lumbar spinal stenosis and compression of the spinal cord and nerve roots, resulting in lumbago and lower limb radiating pain; osteoporotic patients can often cause vertebral compression fractures with minor violence (such as a bump in the car). V. Visceral diseases: abdominal visceral diseases can cause radiating lumbago, such as urinary tract infection lumbago, caused by acute and chronic pyelonephritis, manifested as lumbar distension and pain, and in severe cases, radiating along the ureter to the perineum; urinary tract stones, tuberculosis and other disorders can also cause lumbar pain; inflammation of reproductive organs, such as tubal inflammation, pelvic inflammatory disease, etc., can easily complicate lumbago, retroversion and retroflexion of the uterus, which is also one of the causes of lumbago in women. The uterus is tilted back and flexed, which is also one of the causes of low back pain in women. Serious diseases of reproductive organs such as uterine fibroids, cervical cancer, ovarian cysts, etc., can cause compressive involvement low back pain.
