Phantom limb pain is pain that is felt in the area where an arm or leg has been amputated. Although the limb is gone, the nerve endings at the site of the amputation continue to send pain signals to the brain that make the brain think the limb is still there. Phantom limb pain can be mild to agonizing and even disabling for some. And it may lead to a lifelong battle with chronic pain. Women who have had a breast removed because of breast cancer may also feel phantom pain.
