A septic foot infection requires a blood test to see if the white blood cells and neutrophil fraction are elevated. If they are elevated, it proves that the infection is serious. Take the pus for bacterial culture and drug sensitivity to find the appropriate causative agent and targeted antibiotics, such as cephalosporins, penicillin, levofloxacin or minocycline hydrochloride. Apply topical wet compresses of Ravnol solution twice a day for 20 minutes. After the wet compress, apply topical fusidic acid ointment, compound polymyxin B ointment, clindamycin phosphate gel or oxyfloxacin gel, etc. After the foot infection and pus is treated, you also need to choose the targeted treatment of foot odor drugs, such as terbinafine hydrochloride cream, luliconazole cream, naftifine ketoconazole cream or miconazole nitrate cream.
