Digital infrared thermal imaging (DITI) provides a window into the causes of chronic and acute pain. The source of pain is revealed in the heat pattern on the skin, whether from inflammation, nerves, fractures, or infection.
The thermogram will help your physician diagnose and treat your pain more appropriately.
Here is a collection of images so you can see samples of what will turn up with digital infrared thermal imaging.

DITI is useful for, but not limited to, the diagnosis and evolution of epicondylitis, patellofemoral syndromes, ankle injuries, shin splints, stress fractures, myofascial pain syndromes, spinal pain syndromes, shoulder injuries, foot pain syndromes, and vascular disorders. One of DITI's biggest contributions to sports medicine is in the detection of the posttraumatic pain syndromes of reflex sympathetic dystrophy (complex regional pain syndrome) and sympathetic maintained pain syndromes which can occur after minimal injury. These have traditionally been difficult to diagnose. DITI provides an invaluable window into the autonomic/sympathetic nervous system, which records via somatocutaneous reflex, the sympathetic response to pain and injury.
