Fungal infections on the feet are called tinea pedis, and their treatment varies depending on the condition of the foot: 1. For the vesicular type, foot powder followed by miconazole cream, econazole cream, and bifonazole cream can be used. 2. For the blister type, compounded salicylic acid preparations, 1-3% clotrimazole cream, and also 10% glacial acetic acid can be used. 3. . 4. Those with secondary infection can be treated with antibacterial drugs to control the secondary infection before antifungal treatment. 5. Those with severe tinea pedis with ringworm rash can consider taking ashwagandha, terbinafine, itraconazole, fluconazole, etc. for a short period of time to control its spread and then gradually proceed with treatment without using strong ringworm creams and ringworm drops, especially alcohol preparations, to avoid stimulation and spread. The key to the prevention of ringworm is to pay attention to personal hygiene, family and group hygiene. Socks should be washed and exposed to the sun, feet should be quickly blown dry after washing to prevent fungal growth, and shoes and insoles should be exposed to the sun to avoid fungal growth.
