Anyone who deals with postamputation pain finds basic forms of stump and phantom pain (Table 1). Their occurrence as attacks, as persistent discomfort, or as a combination of these is certainly reminiscent of defined forms of pain. Neuralgia of the trigeminal nerve, for instance, is seizure-like, whether spontaneous or mechanically triggered in its autonomic area, and characterized by intense pain. Causalgia is also paroxysmal and is often supposed to be typical of postamputation pain by implying an incomplete peripheral nerve lesion. Nevertheless, neuralgia and causalgia are much too often considered representative of stump and phantom pain.
