Recently, she has done some oil painting, and used Winsor & Newton's Sansodor (low odor solvent for oil color) to clean her paintbrushes. Does anyone know anything about this and whether or not it is linked to such symptoms?
We are throwing around a bunch of options, including salmonella, influenza, chemical-related sickness (i.e. Sansodor), etc., but it doesn't seem serious enough to see a doctor. She isn't throwing up, just nauseated.
