The statement about what to use to disinfect a foot fungal infection is inaccurate. Foot fungal infection, generally referred to as tinea pedis, can be soaked with sodium bicarbonate solution and treated with antifungal drugs. 1. Tinea pedis is caused by superficial skin fungal infections, the main pathogenic bacteria have red trichophyton, flocculent epidermal fungi, etc., can use sodium bicarbonate solution, potassium permanganate solution, etc. to soak the feet, can inhibit the propagation of the fungus, control the infection, and reduce the foot odor. 2. However, the most important thing in the treatment of tinea pedis is to remove the pathogenic bacteria, quickly relieve the symptoms and prevent recurrence. Therefore, it is also necessary to use external, oral antifungal drugs or a combination of the two. Commonly used antifungal drugs include clotrimazole, miconazole, naftifine, terbinafine, amorolfine and so on. It is recommended that patients with tinea pedis go to the hospital, follow the doctor’s instructions for standardized treatment, do not blindly use their own medication.
