Definition

Phantom limb syndrome is the feeling of sensations in a limb that has been removed. The limb may feel as though it is still attached to the body. This is because the brain continues to get messages from nerves that used to "feel" for the missing limb.

Causes

The exact cause is not known. It is thought that the feelings happen because the brain must rewire itself to adjust to the changes in the body.

Risk Factors

This problem is more common in adults. Other things that may raise the risk are:

• Pre-amputation pain or infection
• A blood clot in the amputated limb
• Previous damage to the spinal cord or the peripheral nerves of the affected limb
• Sudden amputation from trauma, such as an accident
• The type of anesthesia used during the amputation

Symptoms

The symptoms are felt in a limb that is no longer there. Phantom limb syndrome may cause sensations of:

• Pressure

• Numbness, tickling, or cramping
