I had migraines a large part of my childhood. In fact understanding the conditioning portion of TMS came from them because they were some of the first conditioned symptoms I had e.g. they were triggered by smells and being in 'movies' at school . For you youngsters, that is they took us to the gym, dimmed the lights and we watched old fashioned reels, just like at a theater.
I was probably having some sort of symptom need the FIRST time or two they happened, but as we are all very condition-able, all of the rest could have been conditioning. Things that are conditioned are...well, conditioned and it is quite a blow to our thinking waking ego that things in our environment can trigger our TMS...and that are thinking mind can't 'over-ride' this knowledge.
The Good news is that we are re-condition-able. You can advertise in your own head. This is where that talking to ones self that Sarno recommended comes in so handy. True, the younger guys at work think I have gone round the twist, BUT I never have any symptoms anymore. Fear of them can trigger the relapse via conditioning and the nocebo, But it's only gas on a fire...sometimes we have to find the spark.
also @ readytoheal . Virtually all of my TMS relapses 'came out of nowhere' and I was 'ok'...that's part of the mechanism. Usually when I was OK when one of them occurred, I went and sat still and did a review...think, think, think... goT It! I am Not OK... I repressed or was repressing something that wasn't so OK but I didn't think it was a big deal, decided to ignore it and be a positive kind of guy...and ouch my foot hurts.
Learning about ourselves,the unconscious and TMS is a lot like Einsteins metaphor of the watch and God's universe. WE might never be able to open up and exactly know how the watch works, BUT we can through trial error and intuition create a model that reproduces the watch. In this case, YOU are the watch and each one of us needs to figure out how it 'works'. Keep paying attention and you will!!
