Another trick: use that vaporub stuff (Vicks or generic) on your toenails if they are brittle and hard to clip. It softens the nails. I have no idea why. I suppose it would work on fingernails, too.
my MIL told me Vick's Vapo Rub will also quiet a cough if you rub it on the soles of your feet at night, put on socks, and crawl into bed.
i havent ever tried it, so who knows.... but apparently vapo rub has many more uses than we know.. 
Oh God, speaking of that AND feet at the same time....(Stop reading here if you're easily grossed out.)
I developed a fungus on one of my toenails for the first time in my life. I've seen worse, but this is ugly, thick and trying to curl up so much it hurts. I was told that Vick's Vapo Rub is a great toenail fungus remedy. I went to the store to buy it and chickened out for the paint-on stuff. If the store-brand stuff doesn't work, does anyone have experience with Vicks for that purpose?
