Low back pain is a fairly common condition, some people only have pain when they are active, and some people are in pain at any time; Some people will see doctor right away, and some people just don’t pay much attention. However can be relieved by a few simple stretching exercises.
Whether it is a chronic low back pain, or from low back injury, if you often feel pain, not only will make people physically and mentally exhausted. Common causes of low back pain include the following:
Spinal misalignment
Spinal misalignment can reduce the intervertebral nerve foramen opening, compresses nerve roots and produces low back pain and numbness. In our daily activities, there are many postures and movements that can lead to muscle imbalance and trigger spinal misalignment. Misaligned spine can increase pressure on nerve, which can cause pins and needle sensation, burning, or cold sensations in the hands and feet.
Intervertebral disc herniation
Disc herniation is one of the causes of low back pain or sciatica. It is not only restless, low back pain, foot numbness, but also can make people unable to move and work when in severe cases. The intervertebral disc located between the upper and lower vertebrae, consisting of an inner gel-filled like nucleus and an outer fibrous ring. The role of the intervertebral disc is to absorb the pressure on the spine, and has the effect of shock absorption, when we bend the body forward or backward, the intervertebral disc at the same time to make different shapes to match the body’s movements. However, with the increase of age and the long-term weight of the body, the nucleus will begin to dehydrate and deteriorate around the age of 30, the ability to absorb pressure will gradually decrease, and the fiber ring will also begin to degenerate. At this time, improper posture may cause a herniated disc. When the disc of the lumbar spine is herniated, it causes pain in the lower back, whether the pain extends from the back to the buttocks, thighs (lateral or medial), calves (posterior, anterolateral or anterior medial), the back of the foot and the soles of the feet feel numb, and the pain is usually exacerbated when coughing, sneezing, bending over, or holding heavy objects. Patients also feel that it is difficult to stand or walk, the body is often tilted to one side, in severe cases not only pain and numbness present, it may also cause lower limb atrophy and weakness. Lumbar disc herniation is most commonly between the fourth and fifth vertebrae, followed by between the fifth lumbar spine and the first vertebrae, and may also occur in the third and fourth segments. Other diseases in the spine such as spine or spinal cord tumors, spinal stenosis, which may cause symptoms similar to herniated discs, it is necessary to undergo an MRI scan, with a diagnosis rate of 85 to 90%. MRI scans are fairly safe without radiation and do not require hospitalization.
