Phantom Limb Syndrome
What is Phantom Limb Syndrome?
This is the awareness of feelings, frequently together with pain, in an appendage which has been removed. Individuals with this syndrome feel this limb just as if it were involved still with the body and the brain still gets communications from nerves which formerly passed sensations from the absent limb.
Symptoms
Symptoms and signs happen in individuals who have experienced the removal of a limb and individuals who are born minus a limb. These symptoms or signs are felt in a limb that doesn’t exist.
Symptoms and signs can include:
- Pleasure
- Pain – most common
- Feelings of articles of jewelry or clothing
- Feelings as if the limb were still attached as well as operating routinely
Causes
The precise cause of this syndrome is not known. Apparently, the feelings are caused by the brain’s effort to rearrange sensual knowledge after the removal of the limb. The brain might basically be “rewiring itself” in order to correct the change to the body.
Risk factors that can raise the odds of developing this syndrome include:
- Pain before amputation. If pain was in the limb prior to removal, the individual is most likely to feel phantom pain following removal
- Blood clot in the removed limb
- Damage previously to the peripheral nerves or spinal cord which worked with the affected limb
- Children less commonly than adults
After an amputation, it is vital to inform the physician if the individual is feeling pain or other sensations. The earlier treatment is begun generally the chances of success improve.
No medical tests can help in diagnosing phantom sensations. The physician will do a medical history, a physical exam and will want to know about symptoms, circumstances and signs that have happened prior to as well as after the limb removal.
Treatment
Auspiciously, the majority of cases of this syndrome are infrequent and brief. For individuals who do feel pain that is persistent, the treatment may become challenging.
Medications
Certain drugs which are frequently used to treat this syndrome consist of:
- Antidepressants – used for treatment of depression, but can be supportive in pain with phantom limb when used at doses that are low
- Chlorpromazine – used for treating schizophrenia, but can be supportive in this situation also
- Anticonvulsants – used in controlling seizures, but can also be supportive in this situation
- Opioids – powerful pain killers – for instance morphine
- Baclofen – relaxes muscles and are used in treating pain of nerve damage
Electrical Nerve Stimulation
In some cases, electrical stimulation of the nerve can be tried. Examples consist of:
- TENS or “transcutaneous electrical nerve stimulation” – tiny current of electricity is sent thru the skin to points along the pathway of the nerve.
- “Transcranial magnetic stimulation” – magnetic pulse that is strong is sent thru the scalp into the brain.
- Stimulation spinal cord – electrode inserted and small electric current is sent to the spinal cord for pain relief.
Other Approaches – other approaches can include:
- Regional sympathectomy – surgical method where selected nerves near the spinal cord are interrupted affecting the awareness of localized pain.
- Relaxation and meditation techniques
- Hypnosis
- Biofeedback
- Massage
- Exercise
