I have decided to write about Phantom Limb Syndrome Because i have Phantom limb symptoms after a spinal a nerve injury. 
Phantom Limb Syndrome is the perception of sensations including pin in a limb that has been amputated. It feels as if the limb is still attached to the body, because the brain continues to receive messages from nerves that originally were carried impulses from the missing limb.
The cause of this syndrome is mostly unknown although it is believed that it is the brain's attempt to reorganize its sensory information following the amputation. The brain just has to essentially rewire itself to adjust to changes.

the Phantom limb Syndrome was first described in 1552 by a french surgeon named Ambroise Paré, who would operate on wounded soldiers and would write about the patients and their pain in the amputated limbs.
