Sometimes a person shows up around me that has a synethic/chemical fragrance that causes me to get a head/neck/back ache. It has happened in a yoga class, and another type exercise class. It can happen in any type of retail/coffee/grocery store. it does not happen often, BUT is most painful when it does. All I can do is plug my nose and get away. There R times when it is a challenge to get away. Also it is a challenge to say something to the person as when I have they OFTEN R offended and get angry. Help someone how do U handle this ???
