It sounds to me like she might be chemically sensitive. The sunscreen story particularly points to that. I have been very chemically sensitive all my life and it's unpleasant at the least and traumatizing at the worst in situations such as encountering wet house paint and then not being able to breathe afterwards. If she is reacting to products with chemicals like sunscreens - that's not really considered an allergy, nor would and "allergist" recognize it as such. They only consider foods, animals, and weeds/pollens as "allergies" and they only test for and treat those things. But many people are highly sensitive to chemicals especially because we are exposed to so many of them on a regular basis - house cleaning products, home remodeling products, etc. Try this sunscreen: Eco Lani - the only active ingredients are micronized titanium and zinc oxide. It's the only one I use. Other drug store brands are loaded with questionable chemicals. It is all organic ingredients, nanoparticle free, hypoallergenic, coral reef safe, paraben free, and somewhat water resistant. If you are in the water for more than 15 minutes you really need to re-apply. But if you are just in the sun it is great. You can get it at Rainbow Grocery in SF or possibly online or at other "health food" stores. If you find that you can apply this to her and she does not get watery eyes - she's chemically sensitive - which means that you need to change all of her body care products (start shopping at Rainbow Grocery in SF or a similar health food store). If this is the case I can tell you the list of products I use that are about as pure as it gets, and they work just fine. They are just a little more expensive. Aubrey Organics is a good line to check out. But I like the Eco Lani sunscreen better than the Aubrey Organics sunscreen. I researched this for years - I'm happy to share my results with you - you can send me a private message. You will also need to protect her from any home remodeling things, wet house paint (even if it is latex), paint strippers, wood stains, all that kind of stuff. And you will probably want to change your cleaning products. Fortunately there are a lot of "natural" cleaning product brands out now: Biokleen, Earth Friendly, etc. Don't use bleach on her clothes. Get Earth Friendly's "Ecos" Free and Clear liquid laundry detergent for her clothes. The way to treat chemical sensitivity is to avoid the chemicals and use natural products.
