Yes, after I developed a condition called, "Multiple Chemical Sensitivity" (MCS). This condition is usually progressive, as the body loses the ability to detoxify all the different chemcials. For instance, the skin is said to absorb up to 60% of whatever you put on it, including perfume & lotions--and any chemicals in them, of which there are a ton. You can try reading up on MCS for some tips & pointers. I'm not saying you have this condition, I'm just suggesting you might find some helpful info to learn what might be your specific allergic triggers. For me, it is musk, mold, mildew, bleach, things like moth balls or those toilet cleaner things that sit in the tank (like 1,000 Flushes, for example) or one biggie, new car odors from the glues they use to put everything together. I got so ill with our new car that I couldn't travel in it even locally for 1 entire year, and that was after leaving windows open, running the heater while the car sat out in the sun (per my doctor); everything. Just had to wait for the toxins to dissapte. Here we had a nice, new car--and I couldn't even go near it! What a drag that was. If I tried to use the car, I would get symptoms like the flu (stinging/watery eyes, congestion, runny nose, itchy & sore throat, itchy ear canals, body aches & pains, severe cough, laryngitis, even chemical pneumonia).
These allergies or intolerances are said to get more sensitive over time than to improve, so you'll want to find out what your triggers are and stay away from them as best you can, in order to prevent it to progress to a worse state with more allergic responses every time you turn around--if you were to have or develop MCS. I started out just being allergic to some perfumes. Now years later, I seem to be allergic to much, much more.
I find that some things trigger it for me, and some things don't. But for the most part, I try to avoid artificial chemicals as much as I can, except for those days when I really, really want to have a perfume on--then, I will chose one that doesn't give me a headache or other symptoms. If I were to wear it every day for a year or so, I would likely develop toxicity to it and no longer be able to wear it.
As for candles, I can't tolerate scented candles, either real or battery-operated. But I can use certain scented wax melts, such as balsam. I can't use others, such as a new one I wanted to try, mango-citrus. Ah, shucks.
Hope that info helps you figure things out. Good luck!
