I had bad hands when I was a young mum and my farming father in law sprayed my hands blue!!! it was stuff he used on his sheep and prob expensive stuff too, not sure if it worked or not but my hands were bad and did get better.....eventually.
My husband just came home with a healthy and healing food book, I know how bad I do get after certain foods and he is slowing seeing what effects things have on him too, looks like things in curry are great, we love a good home made curry, also fruit and veg with exception of some stuff like tomato's, potatoes and peppers.....well that's us but we should avoid loads of stuff, in particular dairy, red meat and gluten but hay...sometimes its hard.........very hard!!
