Hello, I’ve had four calluses on my left foot for a couple months. As of now they’ve become extremely painful. They hurt when I walk on them and randomly have episodes of intense throbbing and burning even when I’ve been laying down and doing nothing. They are also inflamed and red. I’ve made an appointment with a podiatrist but I can’t get in until Sept 7th. Do you think they’re infected? Do I need to go to the doctor sooner?
