A large proportion of amputees ( 50 – 80 %) experience the phenomenon of phantom limbs ; they feel body parts that are no longer there.
These limbs can itch, ache, burn, feel tense, dry or wet, locked in or trapped or they can feel as if they are moving.
Some scientists believe it has to do with a kind of neural map that the brain has of the body, which sends information to the rest of the brain about limbs regardless of their existence.
Phantom sensations and phantom pain may also occur after the removal of body parts other than the limbs, e. g. after amputation of the breast, extraction of a tooth ( phantom tooth pain ) or removal of an eye ( phantom eye syndrome ).
