Soak Your Toe
To relieve the soreness, soak your foot in a basin of warm, not hot, water mixed with a tablespoon or two of Epsom salts. Soak your toe for five to ten minutes, once or twice a day.
Some doctors recommend a product called Domeboro Astringent Solution, an antibacterial, anti-inflammatory soak that you can buy without a prescription at most drugstores. Dipping your feet in this solution for 20 to 30 minutes each night should help bring down inflammation so that the nail can grow out naturally.
