### Patient: Hi, doctor. I have this hard, thickened patch of skin on my foot that won't go away. It's been bothering me a lot lately. What should I do?
### Doctor: Based on your symptoms, I recommend a complete physical skin exam performed by a medical professional. They may suggest an excision or removal of the callus, along with wound care management. Additionally, it would be wise to have an examination of your foot to check for any underlying issues. If the callus is severe, debridement of wound or infection may be necessary, or an excision of the skin lesion. Other diagnostic procedures on skin and subcutaneous tissue may be done as well for a proper assessment.
