Phantom limb syndrome is the perception of sensations, including pain, in a limb that has been amputated. People with this condition experience feelings in the limb as if it were still attached to their body. This is because the brain continues to receive messages from nerves that originally carried impulses from the missing limb.

The exact cause of phantom limb syndrome is unknown. It is thought that the sensations are due to the brain’s attempt to reorganize sensory information following the amputation. The brain must essentially rewire itself to adjust to the changes in the body.
