So called Chiropractic "Vertebral Subluxations" do NOT exist! Complete nonsense and quackery. Do not waste your time and money on a 116 year old belief system. These guys will stop at nothing to take your money and make you believe that they are doing some good. No substantial evidence to back up their main method of treatment which is the Chiropractic adjustment. Could do more harm than good, especially when they adjust the neck. Avoid!
