Central Pain Syndrome (CPS) refers to pain that originates in the brain and not in the nerves, which lie outside of the brain.  Pain is ordinarily a protective sensation that causes a person to move away from its cause, such as withdrawing one's hand from a fire. 

In the case of CPS, a source of the pain does not exist.  Instead, the sensory pathways within the brain have been damaged by the stroke.  This stimulates central nerve fibers, which creates a perception of pain.

CPS is a burning, aching, or cutting sensation with a mixture of pain sensations, the most prominent being intense sunburn.  Intermixed with this pain are sensations of cold, "pins and needles" tingling, and nerve proximity.

CPS includes several painful conditions such as pain to one side of the face, shoulder, lower back, arm, hand, leg and foot.  Pain may be moderate to severe in intensity and is often exacerbated by movement and temperature changes, usually cold temperatures.

Spasticity and joint stiffness can contribute to the pain, as limbs contract and expand during movement. 

Also, pain sensations are increased significantly by any light touch.
