Please remember that TMS is not just about stress and conscious emotions... neither about somatization of such conscious emotions.
TMS is about UNCONSCIOUS (unfelt!) emotions (mainly rage and anxiety).
For instance: my much beloved young daughter is killed in a car accident by a drunk driver. I feel intense sorrow, sadness, desperation .... and rage, deep rage against the driver..... and the pain in my legs (back, shoulders, ... doesn't matter) begins. I think that's due to an anatomical lesion in my spine caused by a certain movement or effort. That will be confirmed by the doctor through the "evidence" of a MRI. But perhaps doctors can't find such "evidences"!!
In both cases I can be very suspicious that my pain is due to my "bad emotions" related to my daughter's death. "I have somatizated my deep sorrow, sadness ... and rage".
WRONG !
<Probably your pain is the consequence of your repressed emotions>, mainly rage, against the drunken driver that killed my beloved daughter.
I can feel my rage .... but I can feel just "the point of the iceberg" of my rage, the proportion of rage that is sociabiliy acceptable and that I, as responsible, civilized and rational adult, can manage. My brain is protecting me from the immense unconscious rage... distracting my atention and focusing it over my physical body. Otherwise my behaviour COULD be a truly disaster by the human specie (both the drunken driver and me!!!).
