Fungal Nails

These are often caused by the spread of fungal infections like athlete's foot, or by the use of artificial nails or nail polish. Injury to the nail may be another cause. Fungal nails may become thickened, inflamed, or sensitive, and turn unnatural colors.

Since fungal nails are usually more resistant and more difficult to treat than athlete's foot, topical or oral antifungal medications may be prescribed. Secondary bacterial infections may require antibiotic treatment. Debridement may be suggested and involves trimming, filling, or grinding away the diseased part of the nail. Permanent nail removal is another form of treatment.
