Explanation
A. A lumbar herniated disc commonly causes radiating pain down the leg, known as sciatica. This occurs when the herniated disc compresses a nerve root, often causing pain, numbness, tingling, or weakness that radiates down the leg.
B. Headache is not a typical symptom of a lumbar herniated disc. Headaches are generally associated with conditions affecting the head or neck, not the lower back.
C. Difficulty breathing is not associated with a lumbar herniated disc. Breathing problems are typically related to respiratory or cardiac conditions, not issues with the spine.
D. Blurred vision is not a symptom of a lumbar herniated disc. Vision changes are more often related to eye or neurological issues affecting the brain, not the lower back.
