What are the common causes of low back pain?

The most common low back pain is caused by lumbar muscle spasms or strains. Some low back pain is also accompanied by numbness in the lower limbs, which may be caused by lumbar disc herniation. If the waist is severe intermittent colic, it may also be renal colic, mostly caused by urinary system stones. In addition to the above reasons, gynecological inflammation, abdominal organ diseases, ankylosing spondylitis, tumors, infections may also cause low back pain. The spinal cord is a bundle of nerves that emanate from the brain. It passes through a canal made up of vertebrae and branches out through holes between the vertebrae to reach various parts of the body. The nerves that emanate from the waist merge into a bundle that extends to the two thighs. They are called sciatic nerves.
