Nails yellow from nail polish?

-I took off my nail polish a couple of days ago to find my nails had turned a highly unsightly shade of yellow. How do I get rid of this discoloration, FAST?? Thanks!massage it with fresh lemon few times- vitamin C should get rid of discoloration, or get nail whitner

if for some reason nails stay yellow even if you use whitener, it can be a sign of yeast infection and its very hard to treat, impossible whithout quickly visiting a dermatologist and getting prescription drugs. So the longer you wait the harder its gonna be to treat.
