If an apparent fungus condition does not respond to proper foot hygiene and self care, and there is no improvement within two weeks, consult your podiatrist. The podiatrist will determine if a fungus is the cause of the problem. If it is, a specific treatment plan, including the prescription of antifungal medication, applied topically or taken by mouth, will usually be suggested. Such a treatment appears to provide better resolution of the problem, when the patient observes the course of treatment prescribed by the podiatrist; if it's shortened, failure of the treatment is common.
If the infection is caused by bacteria, antibiotics, such as penicillin, that are effective against a broad spectrum of bacteria may be prescribed.
Your podiatric physician/surgeon has been trained specifically and extensively in the diagnosis and treatment of all manner of foot conditions. This training encompasses all of the intricately related systems and structures of the foot and lower leg including neurological, circulatory, skin, and the musculoskeletal system, which includes bones, joints, ligaments, tendons, muscles, and nerves.
