My symptoms are constantly changing. per Dr Sarno only the sympathetic nervous system can do this so no question it reinforces its all just MBS. Most amusing, well I working to embrace the amusement when it happens, is when they move many times in a matter of seconds. When my brain gets really crazy, eg it moves to some completely new part of my body, I can actually tell it to stop and it does almost instantly. Now I have to tap that ability for the stronger and more persistent symptoms. A big signpost happened yesterday. Watched the Duke Texas A&M game in a big soft couch with virtually no symptoms late at night. a combo that reinforces its my attention to the symptoms and my expectation thats driving and even creating them.
