<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have noticed some abnormal appearing skin on my feet and it is also swollen. I also have a skin rash, acne and my skin is very dry, peeling, scaly and rough. What could this be?  <response>: Based on your symptoms, it seems like you have developed calluses on your feet. This may occur because of repetitive friction or pressure. It can cause the skin to become dry, scaly, and thick, leading to a rash, pimples, or swelling.
