Over the past 20 years, the spine physicians at Spine Care Long Island have been the preferred back doctor for low back pain and neck pain patients from across Long Island, from the North Shore and South Shore of Nassau County and Suffolk County, and from Manhattan, Queens and Brooklyn to the East End. Those with back pain or neck pain often struggle to find a back doctor or spine center that can provide a second opinion for spine surgery and offer nonsurgical treatment for back pain, neck pain, scoliosis (curvature of the spine) and pain symptoms related to a herniated disc. Spine Care Long Island is a regional spine center that provides spinal injections, minimally invasive spine surgery, artificial disc surgery and other advances in spine care.
