Try over-the-counter antifungal nail creams and ointments. Several products are available. If you notice white markings on the surface of the nail, file them off, soak your nails in water, dry them, and apply the medicated cream or lotion. If you have athlete's foot as well as nail fungus, treat the athlete's foot with medicated powders or sprays and keep your feet clean and dry. Trim and thin the nails. This helps reduce pain by reducing pressure on the nails. Also, if you do this before applying an antifungal, the drug can reach deeper layers of the nail. Before trimming or using a nail file to thin thick nails, soften them. You can do this with the following nightly routine: Apply urea cream to affected nails, cover them with a bandage, and wash off the urea with soap and water in the morning. Repeat until the nails soften. Protect the skin around your nails with petroleum jelly. If you have a condition that causes poor blood flow to your feet and you can't trim your nails, see a health care provider regularly to have your nails trimmed...consult dermatologist they will help you
