Back pain, the word is familiar, but when it comes to the doctor, it’s a thing that can give the doctor a headache. Low back pain is a symptom that someone visits a doctor and as soon as they get there, they say, “Doctor, my back hurts so much”. In fact, just one back pain can have very many causes, and it is simple to treat the symptoms and stop the pain, but you have to look for the cause. So, what are the possible causes of low back pain? Trauma: acute lumbar sprain, lumbar strain, lumbar disc herniation, lumbar spine fracture and dislocation, etc. There is often a history of trauma. If the acute phase is not treated in time or improperly treated, it can become chronic low back pain. Rheumatism: Both rheumatism and rheumatoid rheumatism can cause low back pain, and the condition changes with weather and season, often combined with other joint pain. Tuberculosis: Lumbar spine tuberculosis and sacroiliac joint tuberculosis often have a history of tuberculosis, and physical examination and X-ray can confirm the diagnosis. Poor posture: long-term bending labor and work can make the lumbar muscles often in a state of excessive tension, and lumbar muscle strain and lumbago occurs over time. Congenital variation of the lumbar spine: occult spina bifida, migrating spine, spondylolisthesis, etc., can present with lumbar pain, but these variations can only be detected by taking radiographs. Degenerative changes in old age: lumbar spine osteophytes or stubborn osteoporosis. Metabolic diseases: osteochondrosis causes bone decalcification and softening due to insufficient intake or increased consumption of calcium, mostly in perinatal women and women with many children. Tumors: primary tumors or metastases of the spine. Low back pain is not simple, but now it has become a common ailment among young people. Well, in fact, the most common, is because of long-term sitting or high-intensity labor caused by lumbar back muscle strain. To put it simply, is the use of more, low back to give the owner a little information, telling you need to rest. This is today’s “lumbar strain”. The diagnostic term “lumbar strain” has been used clinically for a long time, but the treatment has been slow to develop and confusing. Why is lumbar strain easily misdiagnosed and underdiagnosed? Why is lumbar strain diagnosed and given medicine, but still recurring and cannot be cured? The main reason is that the pathogenesis of lumbar strain is not fully understood. The lumbar muscles and paravertebral muscles maintain the posture of the spine, and the spine is subjected to the greatest force. If you sit for a long time, so that these muscles are contracted for a long time, without stretching and rest, there will be strain, congestion, sterile inflammation, and even later fibrosis and adhesions, at which point pain and pressure points in the lower back will appear. Some patients with “lumbar strain” have been examined and everything is normal. In patients with lumbar strain, the pain can also radiate down the broad fascia of the thigh, but only to the knee area, not to the foot and toe tips, which is different from a herniated disc. Due to the irritation of the nerves innervating the above mentioned area, the patient may feel localized coldness. Some elderly people apply musk cream from the outer thigh of the crotch to the knee joint. In fact, these elderly people put it in the wrong place, metaphorically speaking, this is a broken switchboard but repair the telephone line. Where is the “switchboard”? In the waist. When the urologist examines the patient and touches the patient’s groin with pain, it is easy to diagnose epididymitis, spermatorrhea, etc. Female patients are misdiagnosed with adnexitis during gynecological examinations. Let’s see, a small lumbar strain affects such a large and wide span that it can “fool” orthopedic surgeons, general surgeons, urologists, obstetricians and gynecologists ……. If the pathogenesis of the disease is clarified, there is a pattern that can be followed by combining the age and occupation of the patients in the clinic. Young white-collar workers, drivers, accountants and other people who sit in a working posture and have recurrent pain in the lower back, radiating only to the buttocks or outer thighs, with no major problems on examination or photographs, should suspect this disease. It needs to be specific enough to make a clear diagnosis and exclude the above diseases that make everyone dizzy, it is best to consult a doctor at a hospital and have relevant examinations. Usually, we should pay more attention to the activity of their waist, stretching is a good choice. In addition, the introduction of a kind of lumbar back muscle exercise that may be used by everyone, do a 100-200 every night, the pain of lumbar muscle strain and lumbar disc herniation have a good relief effect.
