If you notice any redness, increased swelling, bleeding,or if your infection is not clearing up, see your health care professional. If a bacterial infection is also occurring, an antibiotic pill may be necessary. If you have fungal nail involvement, are diabetic, or have a compromised immune system, you should also see your physician for treatment.
Research suggests that fungi are sensitive to heat, typically 40–60 °C (104–140 °F). The basis of laser treatment is to try to heat the nail bed to these temperatures in order to disrupt fungal growth. As of 2013 research into laser treatment seems promising. There is also ongoing development in photodynamic therapy, which uses laser or LED light to activate photosensitisers that eradicate fungi.
Treating the feet is not always enough. Once socks or shoes are infested with fungi, wearing them again can reinfect (or further infect) the feet. Socks can be effectively cleaned in the wash by adding bleach or by washing in water 60° C (140° F). Washing with bleach may help with shoes, but the only way to be absolutely certain that one cannot contract the disease again from a particular pair of shoes is to dispose of those shoes.
Topical treatment is also usually recommended for children. One reason for this is that most oral medications aren’t suitable for children. Another reason is that children have thinner nails that grow more quickly, so it’s assumed that treatment with nail polish or creams is more likely to work in children than in adults. White superficial onychomycosis is also often treated with a nail polish or cream.
The most reliable way to diagnose athlete’s foot is to correctly identify its cause. Fungal athlete's foot is relatively straightforward to diagnose and treat. Visualization of the fungus in skin scrapings removed from the affected areas of the feet is a painless and cost-effective method for diagnosis. Rarely, it is necessary to identify fungi in portions of skin removed during a biopsy. If no fungus is found, other causes of athlete's foot must be investigated.
Vicks VapoRub is a topical ointment. Although designed for cough suppression, its active ingredients, camphor and eucalyptus oil, may help treat toenail fungus. A 2011 study found Vicks VapoRub had a “positive clinical effect” in the treatment of toenail fungus. To use, apply a small amount of Vicks VapoRub to the affected area at least once a day.
