I had a corn on my left foot and went through surgery to remove it. The skin was healing slowly, and then another corn developed, so I used a corn cap for about three weeks, and it went away. The skin where I had the surgery is formed, but it feels a little hard now. It wasn't painful before, but lately, its been causing some pain. What should I do now? Should I use the corn cap again?

It sounds like the hard skin on your foot may be due to the formation of another corn. In this case, using a corn cap may not be the best option since it is already causing you pain. I recommend using a salicylic acid-based corn remover solution. Apply it directly to the affected area following the instructions on the package. Additionally, you can use a cushioning pad or insole to relieve pressure on the area and prevent further corn formation. If the pain persists or worsens, it is advisable to consult with your doctor for further evaluation and treatment.
