Is the pain that occurs when the sciatic nerve becomes inflamed through compression. The sciatic nerve is the nerve that runs from the lower back through the buttocks and down the leg into the calf and foot. Inflammation causes sharp radiating pain down the leg. The cause can be due to bulging disc, arthritis, obesity, poor posture, and lack of exercise. Our CRP Pain Relief Program can help to reduce the pain caused by sciatica. A nutritional approach can help to aid the healing process of the body and help create muscle mass when in conjunction with light exercise.
