Low back pain with lower extremity pain: imaging examination cannot detect the problem, or discogenic low back pain Discogenic low back pain is a chronic low back pain disease caused by disorders within the intervertebral disc, such as degeneration, fibrous ring endolysis, discitis, etc. stimulating pain receptors within the intervertebral disc, which occurs in women in their 30s and 40s, accounting for about 10% of clinical low back pain patients. Although it is not as common as lumbar disc herniation, it is easily missed and misdiagnosed because the clinical symptoms are similar to those of lumbar disc herniation and the MRI and CT tests are not specific. In daily life, many people also confuse discogenic back pain with lumbar strain. The two are indeed somewhat alike, both manifesting as intermittent low back pain that can be relieved on its own after lying in bed or resting for a period of time, but there is an important difference in that severe discogenic low back pain is often accompanied by lower extremity pain, i.e., pain in the legs or feet during the onset of pain. However, some patients or people with relatively weak pain sensitivity do not feel this way” If detected early, most patients with discogenic low back pain do not need surgery and can be treated conservatively. Professor Fan reminds that if the low back pain is obvious and accompanied by leg pain, and the cause cannot be detected by MRI or CT, a discography should be done to get effective treatment as early as possible. The majority of young people’s back pain is sitting out: diligently get up, more swimming is a good way to reduce back pain People often say “sit down to rest and rest”, sitting is indeed a rest, but for the waist is an exception. Studies have shown that people are sleeping when the waist is under the least pressure, followed by standing. When people sit, even if they maintain the correct sitting posture, the pressure on the lumbar disc is six times that of lying down. In other words, the pressure on the lumbar discs is even greater if the sitting posture is poor. Most of the clinical young people’s back pain is sitting out. Like Ms. Li dry financial work, the end of the month to do statements, a sitting is 8 hours, most of the people working in front of the computer, sitting posture is often not correct, work a nervous and will let them forget to adjust their posture, over time, the lumbar disc long-term pressure, it is easy to appear lumbar degeneration, tearing, disc herniation and other problems. Maintain the correct sitting posture, soon sit, is very important to relieve the pressure on the lumbar disc. Every 45-60 minutes sitting up to do knee flexion, stretching exercises to soothe the lumbar back muscles; adjust the height of the seat to change the sitting posture, do not always let a point under greater pressure; try to keep the waist straight at all times can always be relatively decompression; in lifting heavy objects rather than bending the knees, do not bend the waist. At the same time, to strengthen the waist function exercise, swimming is a good exercise program, suitable for any age group, and not weight bearing, exercise, but also not easy to cause sports injuries. If there are no conditions, you can do crawling exercises at home at night (just like swimming movements), 30-60 minutes each time, can also achieve the purpose of exercising the lumbar back muscles.
