Phantom limb pain is pain that is felt in a limb that has been amputated or lost. Even though the limb is no longer present, the brain continues to receive pain signals as if it were still there.
This condition is thought to result from changes in the nervous system and brain, where the body’s pain pathways continue to send signals after amputation. Phantom limb pain can begin soon after surgery or develop later.
Symptoms of phantom limb pain may include:
Pain intensity can range from mild to severe and may decrease over time.
The exact cause of phantom limb pain is not fully understood.
