According to relevant statistics, 80% of people will experience low back pain in their lifetime, of which some patients will have repeated low back pain. Low back pain has become a common phenomenon, and many young people are also tormented by low back pain. Low back pain, in fact, is a symptom caused by a variety of diseases, lumbar muscle strain and lumbar disc herniation, which are common causes of low back pain. However, these two problems will bring different manifestations and outcomes, and the response measures will also be different. Let's take an in-depth analysis for you now.
Low back pain appears and it is necessary to distinguish the course of the disease. Usually, the course of the disease is less than 3 months, which is acute low back pain, sudden onset, severe pain, aggravation after activity, relief after rest, and at the same time, limited or dysfunctional activity will occur. If the pain is repeated and the course of the disease exceeds 3 months, it is chronic low back pain, which may not be serious in the usual degree of pain, but it can be acutely aggravated under the action of certain triggers.
When low back pain occurs, it should first be examined to rule out disease factors of important organs. For example, some myocardial infarction will have low back pain as the first symptom, and acute pancreatitis can also cause low back pain. If low back pain is caused by an accident or injury, the possibility of fracture or spinal cord compression needs to be considered. If the pain worsens while lying on the back, or if low back pain is felt at night, a thorough examination should be done to rule out the cause of infection or tumor. In low back pain, if accompanied by urinary frequency or urinary incontinence, a differentiating test for cauda equina syndrome is required.
Most low back pain is physical pain caused by mechanical or chemical stimulation of the spine and surrounding tissues such as lumbar muscles, ligaments, and joint capsules, which accounts for about 85% of the causes of low back pain. In addition, compression of nerve roots or lesions of internal organs can also cause low back pain. If low back pain is caused by spinal and fascial injury or degeneration, it is collectively referred to as primary low back pain, accounting for more than 90% of low back pain cases, and the main causes are lumbar muscle strain, acute sprain, fasciitis, ligament injury, articular process disorder, lumbar disc herniation.
Psoas muscle strain is the damage of the lumbar muscles and related soft tissues, the psoas muscle, does not refer to a certain muscle, but a general term for tissue structures such as the latissimus dorsal muscle, psoas major muscle, vertical spinal muscle, and fascia in the lumbosacral area. The so-called strain injury is not overactive, but a disorder of the coordination relationship between the psoas muscles. Because the psoas muscles are interlaced bundles of tissues that cooperate with each other, they help the spine and intervertebral discs to support the body and complete various activities. Maintaining a certain position for a long time will cause psoas muscle tension, so sitting for a long time will also cause psoas muscle strain. In addition, cold and humid environments, or aseptic inflammation of the lumbar muscles, are also related factors leading to psoas muscle strain.
According to these characteristics, psoas muscle strain is divided into 2 types, 1 is a labor type of psoas muscle strain, mainly occurring in athletes or manual workers and other people who often use waist strength. The other is static psoas muscle strain, which occurs mainly in sedentary people such as office employees or drivers. These people, 1 side of the lumbar muscle, are often stretched and have uneven force, resulting in psoas muscle strain. In addition, if the mattress is not properly selected, causing the middle of the spine to sink, the body is curved when sleeping, causing the load on the tissues around the spine to increase, which will also lead to psoas muscle strain. Low back pain due to psoas muscle strain, usually with the habit of poor posture, fixed tender points, and relatively shallow, imaging examination does not show disc herniation or nerve compression, and low back pain does not worsen when coughing or sneezing. This type of low back pain, if the pain point closure treatment, can obtain analgesic effect.
Low back pain caused by lumbar disc herniation, the pain site is mainly concentrated in the middle of the waist, when the pain position is pressed, there can be radiating pain in the lower limbs, and the low back pain caused by lumbar muscle strain is mainly muscle pain on both sides of the lower back. The lumbar disc is herniated, and the painful area can start from the buttocks and gradually radiate to the back of the thigh, the outside of the calf, the back of the foot, and the outside of the plantar. Low back pain caused by psoas muscle strain, the pain site is mainly concentrated in the waist, usually there is no leg pain, especially pain below the knee joint. Finally, it is necessary to remind that these characteristics can only initially distinguish the causes of low back pain, and the specific diagnosis must be based on relevant medical examinations, such as magnetic resonance examination, in order to accurately determine the cause of low back pain.
