You might want to try applying clove oil to the areas. It tastes bad and is antiseptic. I have used it on my rats on tumor stiches, barbering areas, and wounds. Obviously, don't use it on areas that are too compromised-infected, draining, etc... The oil must be therapeutic grade; I recommend Young Living brand. Young Living's oils are edible (if they have a food name, like basil or clove or tangerine).Try a natural food store. Good luck!
