Symptoms and manifestations of lumbar disc herniation include low back pain, radiating pain in one or both lower limbs, abnormal muscle strength in the lower limbs, sensory abnormalities, and dysfunction of urination and defecation.

The main symptom of lumbar disc herniation is lumbar pain, one or both lower limbs will have radiating pain after the nerve root is stimulated, the pain is related to the position and activity, usually aggravated after activity or exertion, and improved after bed rest.

In severe cases, urinary and fecal dysfunction may also occur.
