I forgot to include what Steve posted. Here it is:
I think you do know what the conflict is (the repressed emotion such as anger, guilt, rejection, desertion, a perfectionist personality, physical or emotional abuse from a parent or sibling or others, etc.).
But if it's too emotionally painful, or taboo, or unthinkable, then you can't allow it to surface, thus the physical symptoms. It wants to be let go, but the TMSstops it in its tracks.
You don't have to know what "the" thing is that is causing your pain, or unpleasant symptoms. Over the past 12 years I've seen people get worse by trying to find the magic healing bullet. But it doesn't usually work. And--if you read the new Foreword that Dr. Sarno wrote, he said it was "fruitless" to try to make the unconscious become conscious.
So, I tell people to look at your current life, and to forget the past for now. Your past is what got you here, it formed your personality, and how you respond to stress in your adult life. But it's gone, temporally. So you have a certain Type T persona, and your current life has you under the gun. As I wrote, I believe it is all about relationship. Check your current relationships, and let go of the past ones. Your TMS is there due to some fragmenting of a relationships, or relationships.
TMS occurs because of a reaction. Your physical body is reacting to something. If your body didn't react, then you wouldn't have any symptoms. But the presence of TMS shows that your body is responding. The response is to over stimulation. Most people can recognize a physical reaction to stress, and tension from stress. But they usually aren't aware of "how much" they are responding due to repression and ego. The ego covertly hides how much things are bothering us. The ego is also the thing that causes the reaction, or response. If we placed no attachment to the criticisms or rejections, in relationship, there would be no TMS. The ego is the thing that causes the over reaction.
So you have TMS because you are reacting to life. How you are reacting is how you learned to react as a child. You can change all that through letting go. Letting go is a book in itself, with many ways, and many takes.
Healing is a personal thing, in that, no one can show you how to forgive, or to have faith or belief. No one person can tell someone how to have courage and strength. Those things come through personal revelations within the self.
