Patients with lumbar disc herniation can experience weakness in the legs and feet. After the occurrence of lumbar disc herniation can usually appear back pain, sciatica, foot numbness and other symptoms, relatively early. If the herniated disc is further aggravated and the disc is herniated for a longer period of time, the nerves will be compressed for a long time, and the feet will become weak. At this point, the herniated disc is already more serious, and has already had an adverse effect on the spinal cord, leading to nerve damage, resulting in bilateral lower extremity weakness. At this point, conservative treatments may not be able to achieve good results, and surgical treatment will eventually need to be considered. Surgical treatment requires complete removal of the herniated disc, completely relieving the compression on the spinal cord and providing a better chance for nerve recovery. If the condition is prolonged, the spinal cord nerve damage may not be fully recovered and lower extremity strength is poorly restored. Even then the herniated disc needs to be surgically removed to provide a favorable environment for nerve recovery. In cases where lower extremity weakness is more pronounced, surgery should be performed as soon as possible to relieve the compression as soon as possible.
