They don't like to admit they don't know.That's really sad. There's a hand condition often called "housewife hands" that's basically an allergic reaction in the skin of your hands to constant water and chemical exposure. Once it starts it never goes away completely. Women are also more prone to lung cancer regardless of smoking status because they're exposed to more inhaled chemicals. You'd think a good doctor would never say it's "in your head", but instead say "I don't know but let's keep trying to figure out"
On the plus side due to allergies I have discovered a world of cleaning without chemicals. I use natural goat milk soap* for washing dishes, no more alligator hands. I also use similar soap for shampoo and shower. Toothpaste has formaldehyde, used to make my mouth burn, so now I use a tooth powder that makes my teeth feel as slick as if I just came from the dentist. And I use baking soda and vinegar (separate!) for cleaning the bathroom and kitchen.
