A herniated lumbar disc may cause paralysis, but the probability of this happening is relatively small, and most people do not show signs of paralysis with prompt treatment. Lumbar disc herniation is a relatively common clinical condition, especially mild lumbar disc herniation, which occurs in many people and does not have any symptoms. In more serious cases of lumbar disc herniation, the protruding nucleus pulposus will compress the nerves, and if it is compressed for a long time, the damage to the nerves will be serious, which will lead to sensory and motor disorders in the area innervated by the compressed nerves, and with the further aggravation of the compression, paralysis may eventually develop. Therefore, when early detection of lumbar disc herniation, attention should be paid to protect the lumbar region to avoid aggravation of the condition; if symptoms such as lumbar pain, leg pain, etc. occur, should consult a doctor in a timely manner, and follow the doctor’s instructions to carry out the appropriate treatment, so as to avoid the progression of the condition leading to limb inactivity, urinary and fecal disorders and other symptoms of paralysis.
