Are there any dermatology clinics in Hanam that can treat corns?

At some point, I started feeling something strange on the sole of my foot, but I didn't think it was a big deal, so I just endured it.

But now that it's been almost a month, the feeling is getting worse.

I wondered if it might be a corn, which I'd only heard about, but since it didn't hurt, I left it alone again.

However, starting last week, it started hurting even when I walk, so I think I need to go to the hospital now.

Since both my workplace and home are in Hanam, I'm planning to go to a dermatology clinic there.

Are there any clinics that welcome corns, not just cosmetic treatments?
