I am a 29 year old woman who is in pretty good health. For the past couple weeks, I have been having pain on the ball of my foot in 2 areas. It hurts when I walk on it, and just in general. I was thinking it could be calluses. I have been putting a calluses removal pad on it for almost a week now. It doesn’t seem to be helping that much. Do you have any ideas on what it could be? I have flat feet. Sometimes I have pain on the inside of my foot when I walk. Could a calluses press against something, causing pain on the inside of my foot? I haven’t been to a podiatrist yet. Do you think it is necessary for me to make an appointment? What would they do? Thank you so much for taking the time to respond back.
