Phantom pain is a sensation of pain that feels like it is coming from a body part that has been amputated or is no longer functioning. People experiencing phantom pain may feel discomfort, burning, or itching in the area where the limb used to be, even though it is no longer physically present. This phenomenon can occur after the loss of limbs due to injury, surgery, or conditions like diabetes. The exact cause of phantom pain is not fully understood, but it is believed to involve changes in the nervous system and the brain's representation of the body. Treatments may include medications, physical therapy, or techniques like mirror therapy to help manage the pain.
