As a free community service, this Spine Center of Excellence mails out Home Remedy Books on a limited basis to residents in the region. Home remedy books include information about the spine center, instruction on how to use the exercise book, various exercises to help alleviate back and neck pain, and other home remedies.



For those back and neck pain sufferers who have exhausted nonsurgical treatment options, spine surgery may be the next step in resolving a spine problem. Because spine surgery is a serious decision, it is a good idea to obtain a second opinion from a board-certified and fellowship-trained spine surgeon before undergoing surgery.
