First, mix 1 cup of your chosen vinegar with enough water to soak your feet in. Soak for 15 minutes, and then pat dry with paper towels. Follow this by adding several tablespoons of baking soda to enough water to soak your feet in, and soak for 15 minutes. Pat feet completely dry with paper towels. Do this twice a day. The idea is that the vinegar will kill off the fungus, while the baking soda will then inhibit the growth of more.
Hematomas under the nail bed are large red, brownish, or black spots that occur after a trauma such as slamming a toe in a door or hitting a finger with a hammer. Caused by burst blood vessels under the nail, hematomas will grow out with the nail. However, if a red or black spot occurs under the nail without trauma, it is important to have it checked out by a doctor as it may be melanoma.
