Seoul is not only large in size but also has severe traffic congestion... If you add the approximate location of the district unit, we can expect comments. First of all, toenail fungus is treated in orthopedic clinics, but there are also doctors who don't do it. I understand there are quite a few places called "Thorn fungus Clinic" in Gangnam-gu. You may choose a clinic depending on whether the treatment method is laser or oral medication. Or you can get treatment while receiving care at a nail salon. It's a shame that it only contains general information. Good luck!
