What is Sciatica Sciatica is not a specific disease, instead it is a condition characteristic of several different disease. Simply put it is a mild to intense pain in the left or right leg. Sciatica is caused by a compression of one or more of the five sets of nerve roots in the lower back. These compressions are typically caused by a disc rupture or bone spur in the lumbar spine. It causes pain, numbness, tingling, and weakness in the arms or legs. Everything You Need To Know About Bone Scans A bone scan is a study done to show problem spots on the spine. A radioactive chemical, sometimes called a tracer", is injected into the bloodstream. The chemical quickly attaches itself to sections of the bones that are actively making new bone. Images are taken of the skeleton, several hours after the shot. A bone scan can show problems such as fractures of the spine, infection, and bone tumors. It can also be used to resolve bone density and the bone-thinning condition of osteoporosis.
