Major low back pain that occurs in the spinal cord and nerve roots
Low back pain caused by changes in intervertebral discs, intervertebral joints, and ligamentum flavum is estimated to account for 15% of all low back pain. 
â–º Disc herniation
    This is a state in which the nucleus pulposus protrudes from the inside of the annulus. When the hunch is back, the intervertebral disc will be pushed back. It is important to change the posture frequently and try to avoid maintaining the same posture for too long, so that the disc is pushed to the rear.
â–º Spinal stenosis
    This is a narrowing of the space of the spinal canal through which the spinal cord passes, and symptoms of lower extremity pain or paralysis. It has two types. One is that the deformed intervertebral disc (nucleus pulposus) is pressed from the abdomen to the back, and the other is that the deformed ligamentum flavum and the intervertebral joint are pressed from the back to the abdomen. If you feel genital discomfort, difficulty urinating, pain in the lower extremities or paralysis, you should seek medical attention as soon as possible and receive a precise examination.
â–º Sciatica
    The pain symptoms from the extension of the ankle joint to the inner thigh and the lower leg are mostly caused by the contraction of the sciatic nerve caused by the contraction of the piriformis. Relaxing or stretching the muscle directly can alleviate the symptoms.
Muscle sclerosis is the fuse of pain
    Persistent stress can cause muscle hardening, and the associated blood circulation is stagnant (ischemic), making it impossible to obtain a supply of oxygen and nutrients. If this state persists for a long time, the painful substance (toxin) will accumulate, irritating the nerve line and causing inflammation. This inflammation is the root cause of pain. The brain will harden the pain to protect it, but it will promote the muscles to harden, worsen the blood circulation, and fall into a vicious circle.
â–º pain points
    After the ischemic state is chronic, the muscle fibers gradually become stiff. This part is called the pain point, it will become the "earthquake", and pain and paralysis may occur in the distance. When you pressurize the pain point, the pain can be greatly reduced, and the softness and muscle strength of the muscle can be restored.
Body posture will vary depending on the center of gravity of the sole
    There are 208 bones in the human body, of which 56 are in the foot, accounting for about a quarter, and can transmit the information of the ground tilt or undulation to the brain. When the center of gravity of the sole is changed, the body posture changes. The structure of the foot was originally supported by the heel, but many people used their toes to bear weight and the toes were bent into a "<" shape. When the toes are forced, the sympathetic nerves are activated, which easily stimulates emotions such as nervousness, anxiety, and anger.
