Pain can either be relegated to a specific part of the body or spread to the entire body. It is typically constant, and may be moderate to severe in intensity. Those who are afflicted describe it as being stuck in a loop of pain. It is often made worse by touch, movement, emotions, barometric pressure and temperature changes, usually cold temperatures along with many other similar 'triggers'. Cold temperatures regularly make the burning pain worse in certain body parts. Burning pain is the most common sensation, but patients also report pins and needles, pressing, lacerating, aching, and extreme bursts or constant sharp or unremitting excruciating pain. Individuals may have reduced sensitivity to touch in the areas affected by the pain, as if the part is 'falling asleep'. The burning and loss of sense of touch are usually, but not always, most severe on the distant parts of the body, such as the feet or hands, spreading until it is in some cases felt from head to toe. Usually the burning pain in body parts is a result of old injuries that seem like they should have healed long ago, yet the pain lingers on and even years afterwards. For some patients with intense affliction, there often can be unremitting nausea, causing vomiting. The pain can also bring on hyperventilation. Blood pressure can rise due to the pain.
