80% of people in modern society suffer from low back pain. As we age, osteoporosis in the elderly causes low back pain, while long sitting computer users and long-time drivers often cause low back pain and even herniated lumbar discs. There are many reasons for low back pain, and the culprit is not always a herniated disc. Let’s take a look, what causes low back pain? 1, cold, injury Due to long-term cold in the waist, resulting in the atrophy of the surrounding blood vessels, affecting local blood circulation, resulting in low back pain. In addition, women with rheumatoid arthritis are often attacked by wind, dampness and cold during menstruation or childbirth, resulting in long spinal spurs and inducing lumbago. If the waist has been injured, may also induce lumbago, or induce lumbar disc protrusion. 2, lumbar muscle strain Long-term standing operations such as textile, printing and dyeing, hairdressing, sales and other work of women, 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, can also lead to lumbar muscle strain and caused by lumbago. Often carry heavy objects, lumbar overload, prone to spinal scoliosis, resulting in lumbar muscle strain and lumbago. 3, lumbar spine lesions Most commonly seen in older women, as they age, the symptoms of lumbar spine nerve compression will increase, due to degenerative lesions caused by pseudospinal slippage is a more common lesion, easily causing lumbar spinal stenosis, compression of the spinal cord and nerve roots, resulting in lumbago and lower limb radiating pain, often caused by osteoporosis of the vertebral body collapse fracture. In addition, the formation of bone redundancy can also cause stiffness of the spine, which can lead to persistent low back pain. Due to trauma, long-term strain, strain injury, uncoordinated exertion, improper posture and other causes of intervertebral disc tissue degeneration, rupture of the fibrous ring, protrusion of the nucleus pulposus from the breakage, compression of the adjacent nerve heel, spinal cord, resulting in edema of the surrounding tissue, spinal stenosis, scoliosis and other causes of low back pain. 4, urinary tract infection Patients with urinary tract infection will experience lumbar pain because urinary tract infection can be infected by bacteria and viruses due to untimely or incomplete treatment, and the bacteria and viruses entering the lumbar region will lead to lumbar infection, causing lumbar disease and lumbar pain. It is common in women, because the urethra of women is short and straight, and the outer opening of the urethra is close to the anus, there are often E. coli bacteria parasites, and because of the physiological characteristics of women, there are more chances of contamination of the urethral opening, and if hygiene is neglected, urinary infection can easily occur. Low back pain is mostly caused by acute and chronic pyelonephritis, manifested as lumbago and swelling, and in severe cases, radiating along the ureter to the perineum. In addition to urinary tract infections, urinary tract stones, tuberculosis and other disorders can cause low back pain. 5, duodenal ulcer 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. 6. Kidney deficiency Kidney deficiency causes low back pain. It is painful as the whole waist is vaguely painful, sore and weak. In Chinese medicine theory, the waist is the internal organs of the kidney, and lumbago caused by kidney yang deficiency is manifested as cold pain in the waist, which is manifested as cold pain in the waist and soreness and weakness in the waist and knees. 7, contusion, sprain Sprain is an acute sprain of the soft tissues of the lumbar region including muscles, ligaments, fascia, joints and synovial joints. It is mostly seen in young and strong people. Mainly due to limb overload, incorrect posture, uncoordinated movements, sudden loss of footing, violent lifting of heavy objects, activities without preparation, excessive range of activities, etc.. Once a lumbar sprain occurs, the patient immediately has a stiff back, bending and rotation in a difficult situation, severe and widespread pain, muscle spasms, coughing or sneezing will add to the pain, it is difficult to walk, and sometimes the patient still needs to be assisted by family members or carried to the hospital. Therefore, low back pain is not necessarily a herniated lumbar disc, especially if the pain is severe, you should go to the hospital to do the appropriate examination and confirm the diagnosis. Effective treatment of low back pain.
