The constant soreness in the lower back may be related to lumbar muscle strain, herniated discs, and some internal diseases. Long-term exposure to cold in the lumbar region or repeated bending work may cause lumbar muscle strain, fasciitis and other aseptic inflammation, and the symptom of constant soreness will occur. Lumbar disc herniation and spinal stenosis can also cause symptoms of lumbar aches and pains when they cause compression on the spinal nerve roots. Some internal diseases such as chronic nephritis, renal abscess, female pelvic inflammatory disease can also radically cause lumbar soreness. People who are engaged in heavy physical labor for a long period of time and whose waist muscles are in a state of fatigue can also cause pain and soreness. Ankylosing spondylitis can also cause pain when the lumbar spine is invaded. When you sleep at night, the bed is too hard, and the muscles in the lower back are compressed, which can also cause pain and soreness. If the lumbar region is always sore, it is recommended that the patient go to the hospital to improve the examination, clarify the cause of the disease and receive regular treatment.
