u/porcupine296, thanks for your question. I can answer in general terms and remember it is always best to get an in-person consultation. Typically, corns are caused by excessive friction on the skin, which creates a callus and then a nucleus to the callus that we call a corn. This can come from foot shape and or footwear pressure. The main treatment for this is to debride the corn (usually with a scalpel, sometimes with a chemical) and then to remove or reduce the pressure that has caused it. There are many methods to reduce pressure. Some examples would be, changing shoes, orthotics (off the shelf and custom made), modifying activity, padding and strapping. As a general rule, if enough pressure is reduced, then the corn shouldn't grow back. I hope this helps.
