Atlas subluxation causes sciatica

2. What causes sciatica?
Sciatica is typically the result of a domino affect from a misaligned spine. The most common cause of sciatica is a misalignment (atlas subluxation) of the spine that leads to a bulging or ruptured disc in the spine pressing against the nerve roots that lead to the sciatic nerve. However, sciatica also can be a symptom of other conditions that affect the spine, such as narrowing of the spinal canal (stenosis), bone spurs (small, bony growths that form along joints) caused by arthritis, or nerve root compression (pinched nerve) caused by injury. In rare cases, sciatica can also be caused by conditions that do not involve the spine, such as tumors or pregnancy.
