Editor's note: I often feel backache. Is the cause of backache always hard to find? What about low back pain? According to the NHS website, most low back pain and backache may have no special cause, or they are rooted in soft tissues around joints, bones and spine. The characteristics of this kind of low back pain include: it will get better or worse according to the posture, and it will be particularly painful to exercise gently when sitting or lying down, but it does not mean to avoid activities. Excessive rest may suddenly or gradually aggravate low back pain. It may be caused by bad posture or incorrect posture when moving things, but most of the unknown reasons may be minor physical injuries. For example, a sprain or strain may aggravate the pain due to stress and fatigue, and usually it will gradually improve within a few weeks. According to the data of the National Institute of Neurological Disorders and Stroke, many cases of low back pain are related to the degeneration of normal spinal bones, joints and intervertebral discs, and some cases of low back pain are caused by muscle or spinal injury. Strain and sprain: due to excessive pulling, ligaments, tendons or muscles are damaged, resulting in low back pain. Intervertebral disc degeneration: the intervertebral disc is damaged due to aging, losing its buffering function, and the spine is difficult to bend and twist. Intervertebral disc herniation: the intervertebral disc compresses the spinal nerve, causing low back pain and numbness, numbness or weakness in other parts. Sciatic neuralgia: The sciatic nerve extending from the lower back to the foot is affected by * *, causing pain, numbness or weakness in the back, buttocks, legs and feet. Lumbar spondylolisthesis: the displacement of the spine causes pain, stiffness and numbness in the lower back. Trauma: due to sports injury, car accident or fall, the spine is excessively compressed, resulting in disc injury or protrusion and nerve compression. Lumbar spinal stenosis: Nerves will pass through the spinal canal in the spine and extend downward. When the spinal canal is too narrow, it will compress the spinal cord and nerves, causing pain or numbness, which may lead to weakness or loss of feeling in both legs for a long time. Spinal anomalies: including scoliosis, lordosis and other congenital spinal anomalies. Low back pain may sometimes be a sign of serious diseases, including: infection: although not common, it may be related to osteomyelitis, intervertebral disc inflammation and sacroiliac arthritis. Cancer and tumor: rare, mostly caused by cancer metastasis, and a few cases may be tumors on the back. Horsetail syndrome: Chi Mei medical data show that cauda equina syndrome is more common in people over 40 years old who often sit for a long time, spinal degeneration or disc herniation. When the root plexus of cauda equina below the second lumbar segment is compressed, numbness of feet, weakness of lower limbs, limping and even affecting the function of urination and defecation may occur. Abdominal aortic aneurysm: It is caused by abnormal enlargement of abdominal aorta supplying blood to abdomen and legs. Kidney calculi: It usually appears on one side, causing tingling and severe pain. Osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, etc. Methods: Keeping the activities needed in daily life as much as possible, and avoiding the pain aggravated by long-term rest can improve osteoporosis, endometriosis, fibromyalgia and low back pain. Stretching exercises to relieve pain, or walking, swimming, yoga, pilates and other exercises. You can use hot compress or ice compress for a short time to help relieve pain. Sleeping on one's side in fetal position helps to relax the joints of the spine, reduce the curvature of the spine and relieve stress. Correctly supplement nutrition, calcium, phosphorus and vitamin D from daily diet to help bone growth, avoid obesity and increase waist muscles. Under the diagnosis and advice of doctor Yamatonokusushi, use anti-inflammatory painkillers correctly. If the following symptoms appear, it is recommended to see a doctor immediately and feel numb or numb around the buttocks and reproductive organs. Dysuria, uncontrolled defecation, chest pain, fever, unexplained weight loss, swelling or deformation of the waist, the pain has not been alleviated after rest, and even aggravated the pain that began after a serious accident or collision (such as a car accident). Severe pain prevents daily activities. Editor's note: I often feel low back pain, and the cause of low back pain can't be found? What about low back pain?

Severe pain makes it impossible to do daily activities. Kuya Mu Shunyi (Director of Spinal Plastic Surgery) Low back pain with flexion disorder and low back pain without clear pain cause is mostly "pre-flexion disorder low back pain". The pain methods of low back pain can be roughly divided into forward flexion disorder low back pain, backward flexion disorder low back pain and neither of them. Low back pain that can't be detected by medical institutions or imaging examination is mostly low back pain due to flexion disorder. It is very common among people who sit in front of the computer for a long time to work, drive, nurse and nurse. This is because the posture of leaning forward or crouching half places a burden on the intervertebral discs, ligaments and back muscles of the lumbar spine. "Backward-backward-obstructive low back pain" caused by aging or disease Most backward-obstructive low back pain is caused by spinal degeneration or diseases that increase with age, and the feature is that the cause can be found by imaging examination. The diseases that cause this kind of low back pain are: deformed lumbar spondylosis, lumbar spinal stenosis, degenerative lumbar spondylolisthesis, lumbar separation/free spondylolisthesis and so on. Proflexion disorder lumbago and back flexion disorder lumbago and back flexion disorder. Although it is necessary to rest during the attack of acute low back pain, too long rest time will make the joint mobility worse, the abdominal muscles and back muscles decrease and aggravate the symptoms. Therefore, after the pain is less, you should start exercising slowly. It is suggested that people with low back pain due to flexion disorder can do some exercises to expand the distance between the waist bones, or do some backward exercises. If you have low back pain due to reclining disorder, you can do the exercise of bending over and arching your back to relieve the low back pain. In addition, doing a little squat exercise to exercise abdominal muscles and back muscles is effective for any type of low back pain. According to the different types of low back pain, doing proper exercise can relieve low back pain. The representative exercise is tuck gymnastics. Knee-tuck gymnastics: Lie on your back, hold your knees with your hands, pause for a few seconds, and do 10 times or so. Bending, arching, stretching exercise, it will hurt when bending forward, and it will stretch your back when you don't exert yourself, which is backward-leaning disorder low back pain. If you bend forward, you can relieve the pain, but it can be within the range where your body feels comfortable and does not exert any force. If the pain or numbness is not relieved or even aggravated, you should stop exercising and go to an orthopedic examination. It is particularly important to note that most of the elderly have fragile bones and the function of ligaments and muscles declines. If you hardly exercise, it will make your situation worse. The type of pain when the body bends forward is the type of pain when the body bends forward. Doing some reclining exercises can restore the spine to an S-shaped bend. Representative exercises are prone and propping up the body. Squat gymnastics with elbows bent on the floor (Mackenzie gymnastics). Don't use force on your back, slowly prop up your elbow at 90 degrees, relax for a few seconds and let your waist stretch.

If your back hurts more, or your hips or feet are numb, you should stop exercising. ※ This article is excerpted from The Secret of Japanese Orthopedic Doctors Curing Low Back Pain /Hisano Mushunichi (Director of Spinal Plastic Surgery)/Jian Kang Culture.
