According to the magazine “Chiropractic Wellness and Fitness,” sciatica is a condition in which lower back pain is accompanied by leg pain. The sciatic nerve is one of the largest nerves in the body and is comprised of several individual nerves (L4-S3) that originate from the lower back. This nerve can become inflamed or irritated by a lower back subluxation, disc irritation (bulge or herniation) or direct pressure on the nerve itself (typically by the piriformis muscle). Experiencing this type of pain is continual, severe and incites a feeling of desperation. Using the Large Kneebak Pain Relief Solution Pillow under the buttocks to work out the inflammation, will help alleviate pain and provide a measured feeling of comfort and relief.
