I believe that anxiety needs to be placed higher in the symptoms list and I also believe that Multiple Chemical/Food Sensitivities needs to be added. Over my life I had many of the TMS symptoms – IBS – anxiety – TMJ – fibro and MCS. Never all at once but every few years my body would express another warning. When I had MCS it was so severe that we moved 45 miles into the woods away from civilization and I eventually recovered. I was made worse by both allopathic and holistic treatments so I started my own crusade for the why of chemical/food sensitivity. I found hard scientific research that stress allows the blood brain barrier to become more permeable and this allows in chemicals and substances that are not designed to be in the brain and those that are, are in higher concentrations than normal. There is even some research that the way the body detoxes drugs and other toxins is altered during stress. The Israeli army wondered why a person not in a war zone could tolerate a give dose of medication but once they were moved to the front they showed signs of overdose or more symptoms....stress!! I now believe that living in the woods and not working allowed my nervous system to calm and the MCS resolved. This is the same reason people are drug sensitive. When we are under stress the body also releases histamines that can make us not only sensitive to foods but also cause functional gastrointestinal symptoms.
