Detailed explanation-1: -L5 nerve root exits at the L5-S1 foramina. When compressed by a herniated disc, it causes back pain that radiates into the buttock, lateral thigh, lateral calf, the dorsum of the foot, and the great toe.
Detailed explanation-2: -Disc herniation is pathologically divided into 4 stages of herniated nucleus pulposus: 1) bulging, 2) protrusion, 3) extrusion, 4) sequestration.
Detailed explanation-3: -The most common levels for a herniated disc are L4-5 and L5-S1. The onset of symptoms is characterized by a sharp, burning, stabbing pain radiating down the posterior or lateral aspect of the leg, to below the knee. Pain is generally superficial and localized, and is often associated with numbness or tingling.
Detailed explanation-4: -When a C6-C7 herniated disc occurs and the C6-C7 nerve root is irritated, the symptoms usually include neck pain and pain in the arms, weakness in the hands and weakness in the arms, shoulder pain, chest pains, uncontrollable sweating, headaches, and possibly more. Many times, this condition can be misdiagnosed.
