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.
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.
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
The symptoms are felt in a limb that is no longer there. Phantom limb syndrome may cause sensations of:
Shooting, stabbing, piercing, or burning pain
Pleasure, such as from a light touch
The limb still being attached and working normally
Numbness, tickling, or cramping
The doctor will ask about your symptoms and health history. You will also be asked questions about your amputation. This is often enough to diagnose phantom pain.
Phantom limb syndrome is often brief. It can pass on its own over time. Some people may have lasting pain that is hard to manage. There is no one treatment plan that is best. Treatment will be chosen to help control specific symptoms. Options are:
Medicine that may be given to manage symptoms include:
Electrical Nerve Stimulation
Electrical nerve stimulation may help calm nerve signals. Examples are:
Transcutaneous electrical nerve stimulation (TENS)—a tiny electric current is sent through the skin to nearby nerves
Transcranial magnetic stimulation—a strong magnetic pulse is sent through the scalp into the brain
Spinal cord stimulation—an electrode is inserted near the spinal cord to ease pain
Other methods that may help are:
Regional sympathectomy—surgery to interrupt selected nerves near the spinal cord
