Okay, Gail - now I'm going in circles trying to think of an appropriate response to this question
In my opinion, every human being experiences physical symptoms that are caused by emotional repression rather than by some pathological source. This means that learning about what we here call TMS (because it's a convenient term, but it's not really comprehensive enough) is going to be beneficial for the rest of your life - and that includes helping you to recover from actual pathological conditions, faster and better than if you didn't know about the power of our minds to affect our bodies. Read Dr. Gabor Mate - who never mentions Dr. Sarno or TMS - to see what I'm talking about.
So here's the thing - you certainly DO have TMS - one way or another. And I'm not telling you anything you don't already know.
I forget what kind of doc Dr. Rashbaum is - if he provides psychotherapy in addition to examining you I would go for it. But if all he does is examine you in order to assure you that there is nothing pathologically/seriously wrong with you, and then gives you information about TMS that you already know from hanging out here for two months - then it might be a waste of time and money.
On the other hand, if you really, deep down (be honest with yourself)
need that reassurance in order to contradict the "you are damaged" diagnoses you might have received from traditional surgery-happy docs, then you'd better keep the appointment.
Everyone is different (geez, I say that a lot) so truly, no one else can tell
you what you should do. You've got to get in touch with your reasons for making that appointment to begin with, and honestly decide whether those reasons are still there or not.
In my case, I had my MD, two types of PTs, and a naturopath all assuring me that I was quite fit and healthy, but that I seemed to be anxious and overly-sensitized. I never had any MRIs (although a really good friend was convinced I needed one so I could be told that I had stenosis and then join her in getting steroid injections - bleagh). After finding The Divided Mind, it all made sense, and I never looked back. I never saw a TMS doc, because I was absolutely convinced that TMS explained my symptoms. But if I ever heard of a brilliant TMS psychotherapist where I live, I might be inclined to see him or her, because this stuff is not easy to overcome!
