Pain is a distress signal from the body. In this issue, we will focus on low back pain, especially chronic low back pain. Before talking about low back pain, we need to make it clear that there is a difference between pain and ache, and different pains indicate different diseases, and the treatment for different diseases is completely different. Eight common pains are listed: 1, soreness and swelling; 2, hot feeling; 3, pain after a knife cut; 4, burning pain; 5, stabbing pain of pins and needles; 6, tearing feeling of tearing the dead skin of the lips; 7, pain of overcharge; 8, vague pain (dull pain). Options 1 and 8 are injury-receptive pain, options 2 through 7 are neuropathic pain, and if a sensation is interspersed with pain of another nature, it is mixed pain. Once we know these types of pain, we can make self-judgment. But why does pain often occur in the lower back? Because the waist is nearly the midpoint of the human body, improper sitting posture, sedentary injury waist, pain is generated. Initially, lumbar pain can be relieved by hot compresses, which are mostly pain from lumbar muscle strain, and then further aggravated, it becomes a herniated lumbar disc, or even spinal stenosis. These three common pains can be distinguished by self-identifying the different pains, which one does your back pain belong to? The back pain of lumbar strain is a soreness-like pain, while the herniated disc is an over-electric pain, and the pain can even be strung to the feet when the compression of nerves is severe. The pain department treats back pain as a disease, so there are many ways to eliminate the pain, such as radiofrequency thermocoagulation, where we can use a needle to penetrate deep into the nucleus pulposus and shrink the herniated nucleus pulposus by heating it, thus reducing the compression of the nerve. An effective way to prevent back pain on a daily basis is to exercise the back muscles. In the program, Director Fan recommended two exercise methods as a daily health care method to prevent lumbar pain, Method 1: Five-point support method. Lie on your back, use your feet, elbows and head as fulcrums, lift your waist, insist for a few seconds, put it down and relax, one as the completion of a movement. Method 2:Little swallow fly. Prone position, face down, arms with shoulder joints as a support point, gently lift, arms up while gently lift the head, shoulders backward and upward to collect. At the same time, the legs are gently lifted, the muscles at the bottom of the waist contract, try to let the ribs and abdomen support the body for 3-5 seconds, then relax the muscles, limbs and head back to the original position rest for 3-5 seconds and then do it again.
