If you are consistently having breathing and/or headache symptoms when you are exposed to certain smells/chemicals/places, you may have MCS. Unfortunately, if your environment is constantly bombarded with perfumes, shampoos, cleaners, etc. you may feel terrible but not quite realize what is affecting you. At that point you may want to reduce your product use to scent-free and natural/organic options to see if you feel better, then look for a doctor who is open to the possibilities of chemical sensitivities.
