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, most of which are known, but there are still a few unknown causes. The common causes can be summarized into four categories: ① diseases of spinal joints and their surrounding soft tissues. Such as local injury, bleeding, edema, adhesion and muscle spasm caused by contusion and sprain. ② Caused by spinal cord and spinal nerve diseases. Such as low back pain caused by spinal cord tumor and myelitis. ③ It is caused by visceral diseases. Such as uterus and its accessories, tumor infection can cause lumbosacral pain, and such patients are often accompanied by corresponding gynecological symptoms. ④ It is caused by mental factors. For example, hysteria patients may also complain of lumbar diseases, but there are no objective signs, or diseases that cannot be explained by physiological anatomy and pathological knowledge through objective examination and subjective narration. This kind of low back pain is often a manifestation of hysteria.

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 ~ 6 cm, or even higher. After wearing high-heeled shoes, the height of the heel will increase the center of gravity of the body accordingly. In order to stabilize the original balance lost due to the change of the body's center of gravity, the muscle tension of the body, especially the muscle tension of the back, will be readjusted to create a new balance state.

After people wear high heels, because the pelvis leans forward, the gravity line passes through the back of the pelvis, which increases the burden of supporting the weight of the waist, and then the back stretches and lasts for a long time, which will lead to low back pain due to excessive contraction of the back muscles. Every time the heel height increases 1 cm, the extension of the lumbar spine and the contraction of the back muscles will increase exponentially, and the probability of low back pain will also increase.

It can be seen that patients with low back pain should not wear high heels. In order to prevent low back pain, ordinary people had better not wear high heels often. So should patients with low back pain wear flat shoes? In fact, flat shoes are not necessarily absolutely beneficial, and it is more appropriate to choose a heel height of about 3 cm. Therefore, patients with low back pain may wish to change a pair of suitable shoes, which may relieve low back pain.

Can "walking backwards" treat chronic low back pain?

"Walking backwards" means walking backwards continuously. We often see some people "walking backwards" in the morning exercise crowd. Chronic low back pain is caused by insufficient muscle strength and ligament strength of the waist and poor stability of the lumbar spine. The exercise of "walking backwards" can strengthen the strength of back muscles and enhance the stability and flexibility of lumbar spine. When walking backwards, the waist muscles contract and relax rhythmically, which can better improve the blood circulation of the waist and improve the metabolism of the waist tissue, and has a certain therapeutic effect.

Walking backwards is easy to learn. Middle-aged and elderly people can master activities according to their personal situation. Here are two specific methods for your reference:

(1) akimbo posture: stand up straight, hold your chest out, with your hands akimbo, your thumb behind and the other four fingers in front. Press the "Shenshu point" on both sides of the waist with your thumb. (This point is under the spinous process of the second lumbar vertebra, and it is open laterally 1.5 inch). Action: When walking backwards, start from the left leg, raise the left leg as high as possible, move backwards, and move the center of gravity backwards. First, the left foot touches the ground, then the whole foot touches the ground, and the center of gravity shifts to the left leg, then the right leg is changed, and alternately walks backwards. Every time you step back 1, press Shenshu with your thumb 1 time.

(2) Swing arm type: preparation posture: stand up straight, hold out your chest, look straight at your eyes, and your arms naturally droop. Action: The action of legs is the same as that of hips. When walking backwards, your arms swing back and forth with the movements of your legs.

Walking backwards can be done every morning and evening 1 time, 20 minutes each time. Generally speaking, after each exercise, you should take a short rest, and the fatigue will gradually disappear. The site should be flat and barrier-free. Try to hold your chest out and raise your thighs as much as possible when exercising.

Is cold weather related to low back pain?

Some people will have low back pain or its aggravation because of the weather change, and some patients' low back pain symptoms will be as accurate as the weather forecast. Cold is one of the causes of low back pain. Cold mainly causes low back pain through the changes of blood circulation such as vasoconstriction, ischemia, congestion and edema in the back. Most patients have low back pain because they stay in cold areas for a long time, or sleep on the cold ground or at the air outlet. Cold can cause muscle contraction, which affects body movements to some extent. Besides, in order to keep out the cold, people wear more clothes and are not flexible. If the waist is violently exercised, it is easy to cause waist injury.

Can playing mahjong cause low back pain?

Playing mahjong for a long time, the back is straight, and the intervertebral disc and interspinous ligament are in a state of tension and rigidity for a long time. After a long time, it is easy to make your back sore and stiff, and you can't lie flat and turn around. Moreover, sedentary will make the pelvis and sacroiliac joints bear a large load for a long time, and the waist lacks activity. Qi and blood are easy to stagnate in the waist, causing qi stagnation and blood stasis, affecting the blood circulation of lower limbs, and numbness of the legs for a long time will lead to muscle atrophy. In this case, the muscles are stiff, and a little activity may sprain or cause other injuries, leading to low back pain.

Is smoking related to low back pain?

Many smokers are prone to low back pain, and the reasons are not clear. It may be that smoking leads to chronic bronchitis, and coughing leads to the increase of internal pressure of intervertebral disc and spinal canal. Injecting nicotine into animals will reduce the blood volume of vertebral body, thus affecting the nutrition of intervertebral disc and making it easy to degenerate. This may be the reason why smokers are prone to low back pain. In addition, smokers are prone to lung cancer, which often metastasizes to the vertebral body. Because of the tumor on the vertebral body, low back pain
