Patients with lumbar disc herniation can experience leg pain, which is a typical clinical manifestation. After the nucleus pulposus protrudes, it can stimulate the dura mater and nerve roots, causing pain in the leg areas innervated by the nerves, or localized skin numbness, and decreased muscle strength in the lower limbs. Some patients may also experience difficulties bending over or walking normally. Additionally, some may have abnormal bowel and bladder function, and exhibit changes in reflexes like hyperactive or absent knee and Achilles reflexes. Diagnostic confirmation can be achieved through electromyography, as well as CT scans and MRI of the lumbar spine. For treatment, patients may be advised to lie flat on a hard bed, use lumbar support, and employ pelvic traction. Additionally, treatments such as massage and manipulation may be recommended.
