Corns about the toes can be very painful. Corns are the result of an excessive amount of force on that part of the toes and the epidermis just thickens up to safeguard itself, then will become so thick that it is then painful. Reasons for that greater force are many and can be as a result of bone deformity, a hammer toe or a bunion. A competent podiatrist can certainly remove a corn, however, if the pressure which caused the corn remains, then it is probably going to return. To get the best results long term, the reason behind the corn must be recognized and that cause taken away. At times that could require surgery to correct the underlying bone or toe deformity. Other times that could require the wearing of cushioning for force off loading from the area. Typically, a noticeable difference in the fit of footwear is the most effective methods for getting force off an area.
One way to self manage these problems would be to take off the pressure. You can find shielding pads that you can use like the toe foams. These are a soft foam made from polyurethane using a cloth lining. They are available in longer tubes which means you or the podiatrist can cut them to the necessary length to put on the toe to cushion and protect it. Several of the toe foams have a doubled thicker area on one side to get more cushioning. They tend to be used more in the short to medium terms as they are soft, they aren't that long-lasting. Should they be useful and require to be used more in the long term certainly they will need to be replaced often. Usually talk about your options with the podiatrist to determine what they suggest as the things they think are your better alternatives over the long term.
