Phantom sensations can vary in intensity and quality. Some people may experience a dull ache or tingling, while others may feel a sharp, stabbing pain. The sensations may also be accompanied by a feeling of warmth or cold, or a sense of movement.
Phantom sensations are thought to be caused by the brain's attempt to reorganize itself after the loss of a limb or other body part. The brain still sends signals to the nerves that used to innervate the missing body part, and these signals are interpreted as sensations.
Phantom sensations can be distressing, but they usually improve over time. There are a number of treatments that can help to reduce the severity of phantom sensations, including medication, physical therapy, and psychological counseling.
