Severe back pain may be caused by muscle strain, lumbar disc herniation and other factors, of which muscle strain usually does not lead to paralysis, while lumbar disc herniation may cause paralysis, but the probability is small. If the factor that triggers low back pain is only muscle strain or fascial inflammation caused by long-term strain, it will not cause paralysis because it does not affect the nerves of the spinal cord. If the trigger for severe back pain is a lumbar spine disease such as a herniated disc, it may affect the nerves and cause paralysis. In general, patients with lumbar disc herniation do not have serious symptoms of herniated discs compressing the nerves, and may experience symptoms such as low back pain, numbness in the lower extremities, and radiating pain in the lower extremities, but will not experience symptoms of paralysis. If the patient’s lumbar disc herniation is severe, leading to disc prolapse, it may compress the cauda equina nerve leading to cauda equina syndrome, with signs of paralysis of the lower extremities. Patients may also experience urinary and bowel problems. If the symptoms continue to be unrelieved, you should go to the hospital in time and standardize the treatment under the guidance of the doctor.
