Ok, i actually have a callus that has formed on my last knuckle at the base of my hand from my middle finger. I have tried many products but it keeps coming back. I am in sales and find it very embarrassing when my clients notice it. Can you recommend anything that will get rid of it for good? I also have one on the outside of my right ankle bone that has been there for a few years. I can live with that one since it is not as noticeable.
