What does it mean to be diagnosed with chronic pain sensitization? What are the long term effects of this condition? Anyone have same as me?

After suffering with this for 7 years i discovered that i have this condition also chronic pain from the area at L4/L5 disc that i damaged in an accident at work. The impact of this damage and getting more nerve pain/back pain over the years has affected my life so much. I have lost my job, am house bound most of the time, limited distance i can walk, need help to wash and dress, lost my dignity, lost my past life. I feel i have had to start my life over again because of what has taken away from me physically and mentally.
