Patients suffering from lumbar disc herniation can show a variety of clinical symptoms depending on age, gender, duration of the disease and the location of the herniation, common clinical manifestations: lumbar pain: more than 90% of patients have this performance. The pain is mainly in the lower back and lumbosacral region, with persistent dull pain being the most common. The pain can be reduced when lying down, and can be increased when standing or sitting. Radiating pain in the lower extremities: it can radiate along the lower back, buttocks, posterior thigh, anterior or posterior lateral calf to the heel. The radiating pain is mainly tingling. The radiating pain of the lower extremity may occur before or after the onset of low back pain, both of which vary from person to person. Lower extremity sensory and motor functions are reduced or even lost due to damage to the nerve roots in the area they innervate. Common manifestations include skin numbness, chills, decreased skin temperature, etc. In severe cases, muscle atrophy or even muscle paralysis may occur. Intermittent claudication: When patients walk, the symptoms of low back and leg pain can be aggravated with the increase of walking distance, and can be relieved only after a period of time in sitting or lying position, which is called intermittent claudication. It is possible that the herniated nucleus pulposus induces this symptom secondary to lumbar spinal stenosis. Cauda equina symptoms: These symptoms are manifested as numbness and tingling in the perineum, weakness in urination, and incontinence of bowel movement.
