The term sciatica refers to a group of symptoms, like pain, tingling, numbness, or weakness that radiates along your sciatic nerve—which typically courses from your lower backtrack to your feet.
The medical term for sciatica is lumbar radiculopathy—a condition of nervus spinalis roots within the lower back that get irritated or compressed, sending pain and neurological symptoms into your lower extremities. You might be surprised to find out that one among the foremost common causes of sciatica may be a lumbar ruptured intervertebral disc.
Let us see how a lumbar ruptured intervertebral disc may result in searing pain in your leg or numbness in your foot.
Herniated discs can irritate your sciatic nerve roots. Your lower back (lumbar spine) carries weight and is consistently in motion, making your spinal discs vulnerable to injury and pain. Any bruise to your disc can cause the inner soft-core (nucleus pulposus) to migrate from its normal position and push against the fibrous outer layers (annulus fibrosus). It is also possible for the soft material to leak by tearing the fibrous rings.
