So today after one of my walks I found a painful lump about the size of a nickel on the ball of my foot. At first it was barely visible but hurt like a bitch. Now it seems to have swollen and still hurts. Is it a callus or something? I googled this and couldn't find anything about it. (Pic is the growth btw)
looks like its just a blister to me, get some moleskin at the drug store
