Phantom limb phenomenon

Phantom limb phenomenon occurs when a person who has had a limb amputated still perceives sensations, such as itching, tingling, or even pain, as if the limb were still present. This happens because the brain and nervous system continue to interpret signals from nerve pathways that once served the missing limb. It’s a complex interaction involving nerve signals, brain plasticity, and how the nervous system adapts after amputation. While the limb is no longer there physically, the brain’s representation of that limb persists, leading to these vivid sensations.
