Phantom limb syndrome is the feeling of sensations in a limb that has been removed. There may be feelings in the limb as if it were still attached to their body. This is because the brain continues to get messages from nerves that used to "feel" for the missing limb.
The exact cause of phantom limb syndrome is unknown. It is thought that the sensations are due to the brain’s attempt to reorganize signals. The brain must rewire itself to adjust to the changes in the body.
Phantom limb syndrome is more common in adults than in children. Other factors that may increase your chance of developing phantom limb syndrome include:
A blood clot in the amputated limb
Previous damage to spinal cord or peripheral nerves that supplied the affected limb
Sudden, unexpected amputation (such as accident instead of planned surgery)
Type of anesthesia used during the amputation
The symptoms are felt in a limb that does not exist. Phantom limb syndrome may cause sensations of:
Shooting, stabbing, piercing, or burning pain
Pleasure such as a light touch
Pressure and feeling of clothing or jewelry
The limb still being attached and working normally
Numbness, tickling, or cramping
It is important to tell your care team if you have pain or other sensation after limb loss. Earlier treatment may improves the chances of success.
There is no medical test to diagnose phantom pain. You will be asked about your past health. A physical exam will be done. The doctor will want to know about the signs and symptoms. You may be asked about the amputation. Diagnosis can be made based on your symptoms.
Phantom limb syndrome is often brief. It can pass on its own over time. Others may have persistent pain. Treatment can be challenging for them. There is no one treatment plan that is best. Treatment will be chosen to help control specific symptoms. Options include:
Symptoms may be managed with medicine such as:
Prescription pain medication
Electrical Nerve Stimulation
Electrical nerve stimulation may help calm nerve signals. Examples include:
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 relieve pain
The following have not shown consistent benefits. However, they may help with some symptoms.
Regional sympathectomy—a surgical procedure that interrupts selected nerves near the spinal cord
