About a month ago, I contracted what I believed to be a fungal infection on my foot, or athlete s foot. An itchy, red scaly rash formed between the two outer toes on my right foot. I bought an over the counter topical anti-fungal cream and used it for 2.5 weeks without any signs of improvement whatsoever (in fact it worsened). After this point I bought an over the counter antifungal powder spray, called Tinactin. I used this for two weeks and again, the infection only worsened. The infection has progressed to a point where I have extreme itchyness in combination with weeping blisters or sores that are mildly painful. My question: I went to a doctor today, she took a very brief (and seemingly disgusted) look at my foot. I told her I had used antifungals to no avail, and so she prescribed me Fucidin cream which contains hydrocortisone and fusidic acid, an antibiotic. She also prescribed me Cephalexin, an oral antibiotic. She didn t explain, but I am assuming she believes the infection is not in fact fungal but rather bacterial? Or that secondary bacterial infection has occurred? I am concerned that while the medications she prescribed me will help with a secondary bacterial infection, without antifungals the underlying tinea pedis will not ameliorate and may in fact worsen. What should I do?
