Thank you for your comment, I was baffled and couldn't find out much online about this. I haven't decided whether or not I'm going to get the shots or not. I will keep this site posted. Thanks again!
Yes. Certain types of chronic pain is a learned response of the spinal cord to peripheral nerve pain. The nervous system can "unlearn" chronic pain if the peripheral pain stimulus is blocked.
However, each pain syndrome is unique based on many factors, like length and severity of pain, location and type of pain stimulus, and the microanatomy of one's spinal cord.
I do hope your doctor's plan works and frees you from this life of chronic pain. Best wishes.
