The sciatic nerve is formed from several nerve roots in the lower back, and goes into the leg. When any of the nerve roots are pinched, it can result in a radiation of pain down the leg called sciatica. Often, the pain is just in the buttock, but it can be experienced anywhere in the leg, and is most frequently felt in the back of the leg. Foot numbness can also be a symptom. Misalignments of spinal vertebrae, or sacroiliac joints, herniated or degenerated discs, muscle spasms, or thickening of vertebrae can cause pressure on the sciatic nerve. The Tru-Align can relieve sciatica by tractioning and realigning the spinal and sacroiliac joints, improving disc problems, opening the spaces were the nerves exit the spine, and relaxing and stretching the muscles.
