Causes of Low Back Pain Low back pain is a common condition, second only to the flu in terms of incidence. According to statistics, almost 80% of adults have experienced low back pain in their lifetime. Long-term pressure overload on the lower back is the main cause of chronic low back pain. What we often call low back pain has several explanations from doctors, it may be muscle strain caused by long-term fatigue, it may be excessive pressure causing rupture of the protective layer between lumbar vertebrae, resulting in nerve compression, it may also be due to degeneration of a certain part of the injury and pathological hyperplasia of its surrounding tissues to achieve balance, etc. 1, lumbar disc herniation and bulge rupture of the lumbar intervertebral fibular ring that plays a protective role, the material in the vertebrae stimulates and compresses the nerve. Superficial rupture is bulging (lighter), and deep rupture is protrusion. 2, lumbar muscle strain The muscles of the lumbar back become fatigued after prolonged tensing and stretching, forming an injurious inflammation. 3, lumbar spine hyperplasia lumbar intervertebral disc degeneration due to long-term injury, the vertebral body will occur pathological hyperplasia, commonly known as bone spurs. 4, lumbar spinal stenosis In addition to congenital factors, intervertebral disc degeneration, can also cause the spinal canal before and after the narrowing of varying degrees, compression of nerves. The five yellow light signals of “premature” spine warning 1, low back pain is the most common and most easily detected clinical manifestations. The pain lasts for several days or years. The pain is felt deeper in the area, aggravated by activity and reduced after bed rest. 2. Numbness of the big toe When putting on shoes, it usually relies on the force of the big toe, so there is a lack of force when putting on shoes, walking, or even toe dragging, and sometimes there is numbness of the back of the foot or the palm of the foot, etc. 3, leg pain The performance of a leg (a few people are two legs) pain, numbness, cold, hot swelling, about 98% of the lumbar disc herniation symptoms of leg pain. 4, waist easily sprained waist is easy to be “stretched”, just bending over to take something or wash your face, get up to fold the quilt on the occurrence of lumbar pain, probably not muscle strain but the signal from the lumbar intervertebral disc. 5, scoliosis If you find that the spine becomes twisted left and right, even without the symptoms of lumbar pain, it may be a pre-symptom of lumbar spine pathology. The most “painful” lumbar injury five kinds of people sitting work, often drive, long-term bending or waist in a fixed position work, super waist thin women, most likely to cause acute and chronic injury to the lumbar muscles and intervertebral discs. So these people should always pay attention to the correct posture of the waist, to prevent overwork, to prevent trauma to the waist and cold, to strengthen the waist muscle exercise.
