Low back pain, also known as “lumbar spine pain”, is a condition in which the main symptom is pain in the lumbar spine or the paraspinal area due to external sensation, internal injury or rubbing and flashing, resulting in the poor flow of qi and blood in the lumbar area, or loss of moistening. This article summarizes the five most concerned issues about low back pain. 1.What are the causes of low back pain? Low back pain is a symptom, not an independent disease. There are many causes of low back pain, and the majority of them are known, but there are still a few causes that have not yet been clarified. The common causes can be summarized into four major categories: ① Caused by disorders of the spinal bones and joints and their surrounding soft tissues. Such as contusions, sprains caused by local injury, bleeding, edema, adhesions and muscle spasm. ② caused by spinal cord and spinal nerve disorders. Such as back pain caused by spinal cord tumor, myelitis, etc. (3) Caused by internal organ disorders. Such as infection and tumor of the uterus and its adnexa can cause lumbosacral pain, and such patients are often accompanied by corresponding gynecological symptoms. ④ Caused by mental factors. If a patient with hysteria may also complain of lumbar disease, but there are no objective signs, or the objective examination and subjective narrative cannot be explained by knowledge of physiological anatomy and pathology, this kind of lumbar pain is often a manifestation of hysteria. 2, can patients with low back pain wear high heels? In daily life, many people like to wear high heels, especially young women. The height of high heels is generally about 4 to 6 cm, or even higher. After wearing high heels, the height of the heel makes the body’s center of gravity increase accordingly. In order to stabilize the original balance lost by the change of the body’s center of gravity, the body’s muscle tension, especially the lumbar back muscle tension, will be readjusted to create a new state of balance. People wearing high heels, because of the pelvic tilt enhanced, the line of gravity through the back of the pelvis, so that the waist to support the weight and increased burden, and then after the extension enhanced, long-term sustained, will be due to excessive contraction of the lumbar back muscles and lumbago. For every 1 cm increase in heel height, the lumbar back extension and contraction of the lumbar back muscles will increase exponentially, and the chance of low back pain will become greater. This shows that it is not appropriate for patients with low back pain to wear high heels, and in order to prevent low back pain, it is also best for the general public not to wear high heels often. So is it better for people with low back pain to wear flat shoes? In fact, flat shoes are not necessarily absolutely beneficial, choose a heel height of about 3 cm more appropriate. Therefore, patients with low back pain may wish to change a pair of suitable shoes, may make low back pain will be alleviated. 3.Can “walking back” treat chronic low back pain? ”Walking back” is continuous backward walking, in the morning exercise crowd, we often see some people in the “walking back”. Chronic low back pain is often caused by insufficient lumbar muscle strength, ligament strength, and poor lumbar spine stability. “Walking back” exercise can enhance the strength of the lumbar back muscle groups, strengthen the stability and flexibility of the lumbar spine. When walking back, the lumbar muscles rhythmically contract and relax, so that the lumbar blood circulation can be better improved, improve the metabolism of the lumbar tissue, play a certain therapeutic role. ”Walking back” action is simple to learn, the elderly can be based on personal circumstances, master the amount of activity, the following two specific methods for your reference: (1) forked waist style: preparatory posture: upright, chest up, hands forked waist, thumbs in the back, the remaining four fingers in front. Thumbs press the “kidney” points on both sides of the waist. (The point is under the spinous process of the second lumbar vertebra, 1.5 inches away from the side). Action: When walking backward, start with the left leg, lift the left leg backward as far as possible, exit backward, and shift the body weight backward. First the left forefoot on the ground, followed by the full foot on the ground, the center of gravity moved to the left leg and then the right leg, left and right legs alternately retreat walking. Each step back, use both thumbs to rub the “Kidney Yu” point once. (2) arm swing: preparatory posture: upright, chest up, eyes level, arms hanging naturally. Action: the legs move the same as the forked waist style, backing away with the arms with the movement of the legs to swing back and forth. ”Retreating to walk” exercise can be carried out every morning and evening once a day, 20 minutes each time, generally after each exercise, a little rest, fatigue that gradually disappears as appropriate. Site to choose a flat, unobstructed place, exercise as far as possible to lift the chest, as far as possible after lifting thighs. 4.Is the cold weather related to back pain? Some people will have low back pain or increased low back pain due to weather changes, and some patients’ low back pain symptoms will be as accurate as the weather forecast, the cold is a cause and trigger of low back pain. Cold mainly causes patients to have low back pain through changes in blood circulation such as vasoconstriction, ischemia, bruising, and edema in the low back. Patients mostly develop low back pain due to prolonged stay in cold areas, or sleeping on cold ground or windy places. The cold can lead to muscle contraction, which affects body movements to a certain extent. In addition, in order to protect against the cold, clothes are worn more and actions are not flexible, so if sharp movements of the back are carried out, it is easy to cause lumbar injury. 5, playing mahjong will cause back pain? For a long time to play mahjong, back straight, intervertebral discs and interspinous ligaments for a long time in a state of tension and stiffness, day after day, it is easy to make the back pain stiff, can not supine and turn. And sedentary will make the pelvis and sacroiliac joints for a long time weight, the lack of activity in the waist, qi and blood easily in the waist stagnation and blood stasis, affecting the blood circulation in the lower limbs, and numbness in the legs, which in time can lead to muscle atrophy. In this case, muscle stiffness, a little activity may sprain or cause other injuries, and lead to lumbago.
