Peach ankle skin cracking dermatitis on the ankle

There is a bump on my right ankle that is commonly called the "peach bone." On that part, there is a white, thick, callus-like or keratin-like substance attached.

Applying ointment makes it look a bit clearer, but if I don't use the medication and wait for a while, it comes back again, and the cycle repeats.

There are no symptoms of itching or pain, but that area is covered with a white coating and looks unpleasant, so I keep picking at it with my fingers.

I took it apart again the day before yesterday, and it ended up like this.

It looks really bad when I don't wear socks.

Although it's summer, I can't wear sandals because of this, so I always wear socks and sneakers.

Are these symptoms eczema?

You shouldn't just apply ointment, right?
