Sciatica is characterized by severe pain that can radiate from pressure on the sciatic nerve, this common problem is also known as a "pinched nerve." The sciatic nerve is the longest nerve in the body, so the pain from sciatica can occur anywhere from the bottom of the foot to the base of the spine, where the sciatic nerve is present. The more severe symptoms of sciatica include actual nerve damage, the inability to walk, stand, or balance, and even loss of bowel and bladder control.
The "pinched nerve" usually occurs because of a spinal misalignment, bulging disc, or a herniated disc. Sciatica can be relieved by spinal decompression by reducing bulging or herniated discs that are interfering and putting pressure on the sciatic nerve. Most of the time, if sciatica is corrected, the nerve damage that has been inflicted will heal after the stress is relieved from the nerve itself.
