Okay, this is probably going to bit WTH. Yesterday while throwing in a few low leg shots and simulated cuts, I noticed something a bit strange on the side of my foot. Basically on the inside I have a small marble sized lump. For the life of me I do not understand why I have not noticed before, I suppose it comes down to having ugly feet. Anyway it does not hurt, I can press on it and have zero pain. Any ideas peeps, gristle or something?
