Whether or not back pain can heal itself depends on the cause of the back pain as well as the degree of pain. For example, if there is only a mild injury to the soft tissues of the lower back, it can be cured on its own, but if it is caused by lumbar disc herniation, large kidney stones, etc., it cannot be cured on its own. 1. Mild soft tissue injury in the lumbar region: for example, in daily activities, the impact of external forces, resulting in mild soft tissue injury in the lumbar region, the lumbar region is only mild pain, no other discomfort, generally can be self-healing. 2. Lumbar disc herniation: due to the herniated disc compressing the dural sac, the outer fibrous ring and the posterior longitudinal ligament of the sinus nerve fibers are stimulated. If the disc herniation is large, stimulation of the dura mater can produce duralgia and lumbar pain, which generally cannot be self-healed. 3. Larger kidney stones: When the stones are large enough to cause obstruction of the renal pelvic outlet, then the urine produced by the kidneys will accumulate within the kidneys, resulting in hydronephrosis. When the pressure inside the renal pelvis is too high, low back pain will occur, and this condition cannot be cured by itself. When back pain occurs, it is recommended to consult a doctor in time, follow the doctor’s instructions for further examination, clarify the cause with the doctor’s help, and carry out targeted treatment.
