Hi, yes feeling unwell after exposure to scents or strong odours makes me think of allergies too. It can also be an indication that your liver is not efficiently clearing chemicals out of your system ( from the naturopathic point of view) and you may find the herb milk thistle to be helpful. Also helpful is reducing the workload clearance wise, so less chemicals around the home, limit alcohol and moderate protein intake, and avoid foods that contain chemical colourings etc. You could also check whether any of the medications you are on affect liver function. You could have allergies or chemical sensitivities; allergies tend to manifest as sneezing, wheezing, itching etc ( though not confined to that) and chemical sensitivities tend to show as nausea, headaches, feeling ill around fumes e.g. After filling the car with petrol or using cleaning agents around the home.
Hope that helps!
