I have been painting my feet to help my dry mouth. I had also been painting my breasts too in hopes of curing an itchy spot I have there. I stopped on the breasts because the hair follicles became irritated, but kept on painting the feet. But it isn't helping my mouth as much. So today I painted my breasts before work, I'm noticing it helping already. Is this psychosomatic or does the paint location really matter that much??
