The lifetime incidence of lower back pain is higher than 60% for people over the age of 40. This means that most people in life have been bothered by low back pain at one time or another. Low back pain can seriously affect the quality of life of the patient. Modern life is fast-paced, and for back pain that is not very serious, many patients choose to endure it rather than seek medical attention. Here I will give you a brief introduction about several common diseases of low back pain so that you can diagnose and treat yourself. 1.Lumbar muscle strain. This is a familiar name, lumbar muscle strain in the textbook of orthopedics should be called lumbar back muscle fasciitis. The people who are more prone to lumbar muscle strain are two, one is the long-term bending work, such as porters, this is easier to understand. The other is a person who works in a seated position for a long time and lacks physical exercise, which is a little more difficult to understand. I sit all day, but I don’t use my back, so how did I get a strain. I often give patients an example, you use your arm to end a very light cup, you do not feel a few minutes, then end a morning, your arm must be sore. We sit in a posture, so the lumbar muscles that maintain the sitting posture continue to contract for a morning, it must be sore, over time natural strain. The characteristics of low back pain caused by lumbar muscle strain are: low back pain is obvious in the morning before getting up, low back pain is relieved after getting up and moving around, and low back pain reappears and worsens after sitting for a long time. Gently tapping on the lumbar area feels comfortable rather than aggravating pain. For the treatment of lumbar strain, if you are in the first group, you should protect your waist and change your work style. The treatment for the second group of people is relatively simple, get up after 2 hours of sitting work and move the waist, do functional exercises for the waist in the evening, lie prone in bed before going to bed and do the two head cocking action. Or check swimming once a week. Take anti-inflammatory and analgesic drugs such as Fotarine orally for a week when the pain is severe. (Those with peptic ulcers, use with caution.) 2, osteoporosis. For patients older than 60 years of age persistent low back pain, back pain, heavy feeling. At the same time there is a slight hunchback deformity performance, and from time to time there is cramping performance. Then the cause of this low back pain is most likely osteoporosis. If you want to confirm the diagnosis you need to do bone density examination. 3.Degenerative disease of lumbar spine. For patients older than 50 years old, persistent lower back pain, not accompanied by leg pain and numbness, the most likely diagnosis is lumbar degenerative disease. Degeneration of the lumbar spine is often preceded by degeneration of the intervertebral discs, which is followed by osteoarthritis of the synovial joints (the proverbial bone spur of the lower back). The diagnosis of the disease can be confirmed by lumbar spine x-ray. 4, lumbar disc herniation. Lower back pain caused by a herniated lumbar disc is usually accompanied by radiating pain in one or both lower limbs (legs), numbness in the legs, or numbness in the toes. The diagnosis of the disease requires the use of CT or MRI. 5. Other causes of low back pain: for example, kidney stones. Kidney stones can also cause significant low back pain, often with sudden onset of pain after activity, severe pain and profuse sweating. The color of urine is red. These are several common causes of low back pain, to give you a brief introduction, so that you have a general idea. For specific diagnosis and treatment, it is necessary to go to the hospital to find a doctor to do a detailed examination, so as to avoid misdiagnosis and delay in the treatment of the disease.
