Foot fungus blisters usually subside spontaneously in about 7-10 days if they are not picked. Tinea pedis is clinically called tinea pedis and is caused by a fungal infection. Common types of fungi include Trichophyton rubrum, Trichophyton spp. and Microsporum ferrugineum. The fungus feeds on the local stratum corneum, which can lead to the local stratum corneum loosening to form blisters, and then repeated scratching due to the patient’s itching to form friction blisters, which then form blister-type tinea pedis. These blisters are usually absorbed by the body on their own in about 7-10 days and gradually dry up and flake off at a later stage. For some large blisters that affect the patient’s quality of life, it is recommended that a sterile disposable syringe be used to extract the blisters after local disinfection, and that antifungal medication be used locally to help repair the lesions more quickly. Patients with foot odor should wear loose and breathable shoes and socks as much as possible, change shoes and socks regularly, and keep local dryness to help inhibit the occurrence of foot odor.
