Nail fungal infections are a very common medical problem. The doctors who will be well qualified to discuss this issue with you in greater detail include your primary care doctor
or your dermatologist
. The fungi that cause nail infections are found throughout the environment including in the soil and also in humid places like shower stalls and locker rooms. Therefore, a big part of controlling fungal infections includes good hygiene and avoiding contact with the places where they breed (wearing shower shoes etc). At the same time it is important to also change socks frequently and to keep shoes clean and dry to prevent encouraging fungal growth. Antifungal creams can help with more superficial fungal infections of the feet, such as athletes foot. However, once the fungal infection settles into multiple nails, causing distortion and thickening, the creams cannot effectively penetrate. Therefore, most fungal nail infection will also require a prescription oral antifungal medication that can be prescribed by your physician. As always the diagnosis and the management of your particular concern will require a physical examination by your personal physician. Setting up an office visit with your primary care doctor or your dermatologist is highly recommended.
