How can my doctor tell if I have complex regional pain syndrome?
Your doctor will make the diagnosis based on your pain symptoms and your physical exam. There is not one specific test that can diagnose complex regional pain syndrome. Your doctor may order a test to check skin temperature and how much blood is flowing to a certain area of your body. If there is a major difference in the results between the affected limb and an unaffected limb, your doctor may diagnose complex regional pain syndrome. A magnetic resonance imaging (MRI) test can show changes in the tissue of the affected limb.
