Post Amputation Phantom Pain

Phantom limb pain is the perception of pain or discomfort in a limb that is no longer there. PLP most commonly presents as a sequela of amputation. The underlying pathophysiology remains poorly understood.

What causes phantom pain?

The underlying root cause of phantom limb pain is not clear, but it originates in the spinal cord and brain. This is believed to be caused by a mixed signal in the brain. After amputation occurs, areas of the spinal cord and brain miss input sensations from where the limb should be. The body takes time to adjust.
