Central Post Stroke Pain
This is a good description from the Pain Felief Foundation's website. With their permission, a link to their information leaflet is given below.
A stroke is the result of loss of the blood supply to a part of the brain and can result in weakness and slurred speech.
Approximately 5% of people who have a stroke will develop nerve pain from the stroke (CPSP). The onset of pain may occur at the time of the stroke but often occurs several months later.
The pain is often described as burning, and also throbbing, shooting or stabbing. The pain is felt in a part of the body affected by the stroke. In this area there is often a loss of feeling.
The precise cause of this pain is unknown. Because the brain is damaged it feels pain when it should be feeling a sensation that is not painful.
Common painkillers have no effect on this pain. Some medications developed for epilepsy and depression also have the effect of reducing pain after strokes. This is quite separate from their use for depression or epilepsy! Relaxation and distraction can also be very helpful.
In 20% of patients the pain gets better over a period of years. In 30% of these, there is a lessening of pain over the first year.
