Tinea pedis is a foot fungus due to fungal infection and appears painful, possibly due to infection or cracking. If pain occurs due to infection, it is recommended to apply topical Revnor solution or furacilin solution topically as a wet compress, along with fusidic acid cream and Bactrim cream for anti-infection treatment, and avoid contact with water. If the pain appears due to dryness and cracking, you can apply topical bifidazole cream topically, seal the package with cling film to promote drug absorption, and give 10%-20% urea cream topically after 5 minutes-10 minutes to promote skin moisturization. Usually, attention must be paid to avoid excessive washing. For patients with recurrent attacks, oral antifungal medication, such as terbinafine, can be administered.
