the only thing i know of is to remove all chances of exposing yourself to chemicals such as all perfumes ,laundry soap with perfumes ,household cleaners things that we put on our bodies everyday such as lotion, body soap etc. are all chemicals when we over due something or exspose our selves to harsh chemicals some of us become allergic and then even the slightest little amount of exsposure makes us react making us sick. im sorry i dont know of any specialist that are covering this topic at this time,but i do know a lady in the area that became chemicaly allergic after being exposed to harsh chemicals in the work place. the company was remodeling the building, painting and glueing new carpet etc.and she became sensetive to everything she cant even leave her home or be exsposed to someone with these types of chemicals on them(soaps,perfumes etc)the only suggestion i would have would to be to contact OSHA and see if they will send you information on quality of indoor air pollution and from there you may get some leads on people/institutions researching this subject.
