If your physician determines that the clinical examination of your back pain has turned up something that merits confirmation or a closer look, he can choose from a wide range of diagnostic tests to be used individually or in combination with others – each will help him determine the best course of back pain treatment for your specific condition. Many of these back pain tests are noninvasive, meaning they do not involve needles or any other intrusion into your body, and they present only a minimum of discomfort in exchange for the information they provide.
