<P> Although dysesthesia is similar to phantom limb syndrome, they should not be confused . In phantom limb, the sensation is present in an amputated or absent limb, while dysesthesia refers to discomfort or pain in a tissue that has not been removed or amputated . The dysesthetic tissue may also not be part of a limb, but part of the body, such as the abdomen . The majority of individuals with both phantom limb and dysesthesia experience painful sensations . </P> <P> Phantom pain refers to dysesthetic feelings in individuals who are paralyzed or who were born without limbs . It is caused by the improper innervation of the missing limbs by the nerves that would normally innervate the limb . Dysesthesia is caused by damage to the nerves themselves, rather than by an innervation of absent tissue . </P> <P> Dysesthesia should not be confused with anesthesia or hypoesthesia, which refer to a loss of sensation, or paresthesia which refers to a distorted sensation . Dysesthesia is distinct in that it can, but not necessarily, refer to spontaneous sensations in the absence of stimuli . In the case of an evoked dysesthetic sensation, such as by the touch of clothing, the sensation is characterized not simply by an exaggeration of the feeling, but rather by a completely inappropriate sensation such as burning . </P> <P> There are a number of hypotheses regarding the basis of occlusal dysesthesia . Some researchers believe the disorder is a psychological one, while others believe it to be a psychosomatic disorder . Joseph Marbach hypothesized that the symptoms were rooted in psychiatric disorders . Marbach suggested that occlusal dysesthesia would occur in patients with underlying psychological problems (such as schizophrenia) after having undergone dental treatment . More recently, two studies have found that occlusal dysesthesia is associated with somatoform disorders in which the patients obsess over the oral sensations . </P>
