NAILS, DEFORMITY IN, WITH DISCOLORATION AND THICKENING: TREATMENT

If you think you have a fungal infection of a nail, you need to see your doctor. Although there are many over-the-counter topical preparations available, they are not usually very effective because they don't penetrate the nail. Instead, they contain the infection in the nail and prevent it from spreading to the skin around the nail. Fungal infections are extremely difficult to treat.
Your doctor can prescribe a treatment called Spornox, an oral medication taken once a day that will destroy the fungus. Treatment may last for at least three months. In the meantime, while the infection cleats up—which may take as long as nine months, or the amount of time it takes your nail to grow out—don't wear nail polish, and wear gloves whenever you immerse your hands in water, since water may cause the fungus to spread, as it thrives in a warm, moist environment.
