Tinea pedis is caused by fungal infections, commonly caused by dermatophyte infections, but of course there are many subtypes, such as alexandrium and albicans. The infection is mainly manifested as erythema and papules on the skin of the foot, which can be accompanied by blisters and flaking, and if it occurs between the toes, there can be skin erosion and oozing, and in severe cases, it can be combined with bacterial infection. Generally speaking, for simple vesicular foot odor, topical medication alone is sufficient, but for combined infections, antibiotic treatment is required. For the blister type, especially the deeper blisters, the topical medication alone may not be able to completely solve the problem, and it is difficult to fully absorb the topical medication, this situation requires oral antifungal medication, fluconazole, itraconazole capsules, terbinafine, etc., depending on the doctor’s assessment.
