X-rays are taken for your own safety. Sometimes bad things show up in x-rays, such as old fractures, arthritis, scoliosis and other problems that are important for Dr. Thwaits to be aware of. Sometimes things we are unaware of such as new fractures, whiplash, ect. can be found. X-rays can ensure your best possible results. Ultimately, x-rays help Dr. Thwaits see what he needs to see to help you.
