Spinal stenosis occurs when the spinal canal narrows and compresses nerves. This pressure often affects the lower back and neck, leading to pain, numbness, or weakness.
ROLE OF THE SCIATIC NERVE
The sciatic nerve is the largest nerve in the body. It starts in the lower spine and travels through the hips and legs, controlling movement and sensation.
HOW A SLIPPED DISC CAUSES PAIN
A slipped disc happens when disc material presses on nearby nerves, irritating the sciatic nerve roots.
