G54: Nerve root and plexus disorders

G54.7: Phantom limb syndrome without pain

We usually feel our body parts because they send information to the brain. The information is processed in the brain. This is how we perceive sensations in our body parts. In the brain, for every part of the body, there is a separate region where the information from that body part is processed.

Body parts can be lost through accidents or by being removed during an operation. Even when a body part is no longer there, the corresponding region in the brain is still there. It can happen that this region in the brain continues to process information. Then it can feel as though the missing body part is still there. It may be that you only feel a particular part of the missing body part.
