Hi Alberta,
Here's reference to the condition your doctor had mentioned:

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3268359/
http://www.ncbi.nlm.nih.gov/pubmed/19712899#
I am sorry you are dealing with this.
Many people with chronic pain have central sensitization.
Also, many have central pain sensitization, along with non-centralized pain, where there is actual tissue damage, etc.
I deal with both.
I hope these articles help?
Did your doctor propose a treatment plan for you?
