Phantom Limb Pain Syndrome
Phantom limb pain is the perception of sensations, usually pain, in a limb that has been amputated. Patients with this condition experience the limb as if it were still attached to their body as the brain continues to receive messages from nerves that originally carried nerve impulses from the missing limb. The exact cause of phantom limb pain syndrome is unknown. It is presumed that the sensations are due to the brain's attempt to reorganize sensory information following the amputation. The brain is unable "rewire" itself to adjust to the body's change. Symptoms are most commonly pain, but can include sensations of clothing, or as if the limb were present and moving.
