Re: Help Please!
Yellow spots in the nails can be a sign of fungal infection. I would recommend you give your nails a break from polish, keep them dry and cut relatively short for a couple of months. If this is your finger nail, it will probably clear up on own and grow out. Toenails are a much bigger problem and the fungus can become chronic and difficult to eradicate. When filing, file all other nails first, then the spotted one, and boil file for 10 minutes if metal or discard and use a new one next time. If it is fungus, it can spread via the file to another nail if you file the spotted one first, then file others. Nail salons violate this "clean to dirty" principle all the time, so I would recommend you do your own nails for now.
