Why does sciatica hurt so bad, and what is actually happening in your body when that sharp, shooting pain travels all the way down your leg?
While you feel the burning, numbness, or weakness in your leg, calf, or foot, the true root cause of sciatica almost never starts in your leg. The sciatic nerve is the largest nerve in the human body, but the actual problem usually traces back to your lower back and intervertebral discs.
In this anatomical breakdown, Jonathan from the Institute of Human Anatomy uses real cadaver dissections in the lab to answer what sciatica is and why it hurts. You will see exactly how bulging and herniated discs in the lower back compress the spinal nerve roots (L4, L5, and S1) that form the sciatic nerve

Common Questions
Why does my sciatica hurt so bad?
Sciatica pain occurs when a nerve root in your lower back is compressed or inflamed by a bulging or herniated disc. This irritation sends pain signals along the entire path of the sciatic nerve, down your buttock, leg, and foot.
What is sciatica and what causes it?
Sciatica is not a disease itself, but a symptom of nerve irritation. It is most commonly caused by a herniated disc, bone spur, or muscle entrapment (like piriformis syndrome) compressing the L4, L5, or S1 spinal nerve roots.
Why do I feel sciatica pain in my leg if the problem is in my lower back?
The nerves that control sensation in your legs originate in your lower spine. When a disc compresses a nerve root at the spine, your brain interprets the pain along the entire nerve pathway down the leg (a dermatome).
Can sciatica pain heal on its own?
Yes, most sciatica cases improve with conservative treatment like physical therapy, core exercises, nerve glides, and time, as the body gradually resorbs the herniated disc material.
