I recommend Gangwha Bonpi Dermatology Clinic.

I went to my local dermatologist to get treatment for toenail fungus. I tried applying nail polish-like medicine in a gel bottle to my toenails, but it didn't work very well, so I consulted them and they said there's a Japanese topical medicine. They also recommended a pill to take once a week. They said I should watch for side effects while taking it because my liver is detoxifying. I'm going to give it a try. They say toenail fungus is caused by the cold because warm blood isn't reaching the tips of my toes. But since my feet feel stuffy when I wear socks, could it be because I go barefoot except in the middle of winter?
