If scoliosis is severe it can affect your heart, lungs, gut, spinal cord and nerves producing a large range of problems from difficulty breathing to difficulty walking. Fortunately this is not common. Many cases of scoliosis respond to conservative treatment (such as bracing) and do not require surgery. Please see my blog posting Does scoliosis cause pain? For more information please contact Dr. Carl Spivak at Executive Spine Surgery. Good Luck!
