Radiating pain down one leg that gets worse while sitting? This pain is referred to as Sciatica but is actually not a medical lumbar condition. It is a symptom of an underlying lower back problem. Sciatica can be the result of a condition such as a herniated disc, spondylolisthesis, or spinal stenosis. BioSkin Back Braces are designed to address Sciatica pain with targeted, vectored compression that alleviates pain and relieves pressure applied to the lumbar nerves.
