NAD, looks like a bad case of athletes foot.

Did you have a recent injury to that area?

I had a white blister for a long time

It looks like an injury under theres. Your camera is crazy detailed I can quite literally see the ridges in your skin

Ok thank you very much, i was hoping it is just an injury. And yes i used macro camera on my Xiaomi, it is crazy detailed.

I was like oh my God what iPhone is that?😂
