My T always says-- the body remembers and if I can just become aware of what body parts get "triggered" I can work to calm their response. It won't make the body forget, just not make them respond so strongly.
I am not saying this is etched in stone, it's just what she tells me. Believe what you will.
There is a book called 'The Body Keeps the Score', by Bessel van der Kolk that is very informative on this subject.
