I am worried because I have developed many wrinkles on the sole of my foot.

Recently, the weather has gotten colder, and walking has become a bit uncomfortable. When I looked at the soles of my feet, I noticed that there were unusually many wrinkles. So I visited the hospital. Suddenly, walking became uncomfortable, and I had many wrinkles on my soles, which seemed strange. The doctor said that this is a rare case and examined me. However, since there has been no improvement, I am making a reservation and waiting to go to a larger hospital. I am curious if there are others who suddenly experience similar symptoms like mine. I am also very curious about how they were treated. I would appreciate it if you could share your experiences.
