I found this article to be very informative on the subject of how chronic pain effects the brain;specifically,how the brain adapts in various situations.
My short term memory is gone. I sometimes lose my words. I find it difficult to focus and complete sentences and tasks, etc. How has chronic pain effected your brain function? Is it the RSD ,the chronic pain,or pain medications that change the brain's gray matter? Could it be a combination of the above stated?
