In some cases of suspected nail fungus there is actually no fungal infection, but only nail deformity. A 2003 source gives a figure of 50%[17] whereas a more recent source claims that fungus is present in 65 to 95 percent of cases.[18] Avoiding use of oral antifungal therapy (e.g. terbinafine) in persons without a confirmed infection is a particular concern because of the possible side effects of that treatment.[17] However, according to a 2015 study, the cost in the United States of testing with the periodic acid–Schiff stain (PAS) was about $148. Even if the cheaper KOH test is used first and the PAS test is used only if the KOH test is negative, there is a good chance that the PAS will be done (because of either a true or a false negative with the KOH test). But the terbinafine treatment only cost $10 (plus an additional $43 for liver function tests). In conclusion the authors say that terbinafine has a relatively benign adverse effect profile, with liver damage very rare, so it makes more sense cost-wise for the dermatologist to prescribe the treatment without doing the PAS test. (Another option would be to prescribe the treatment only if the potassium hydroxide test is positive, but it gives a false negative in about 20% of cases of fungal infection.) On the other hand, as of 2015 the price of topical (non-oral) treatment with efinaconazole was $2307 per nail, so testing is recommended before prescribing it.[18]
Topical treatment (polish or cream) isn’t likely to get rid of a fungal nail infection. Treatment with tablets is considerably more effective and takes less time. But some people can’t take tablets because of the very rare, yet serious risks. How you feel about the pros and cons of the different treatment options is a personal matter. You can also discuss the options with your doctor.

Baking soda has the ability to dry up the excess moisture on your toes, and it will help neutralize foot odor and act as a toenail fungus treatment. Create a paste using baking soda and water and apply it to the toenail. Let it soak for 10 minutes and then rinse off. You can also create a foot bath by mixing a bucket of water with baking soda and letting your entire foot soak. Check out these other effective home remedies for smelly feet.

When athlete's foot fungus or infested skin particles spread to one's environment (such as to clothes, shoes, bathroom, etc.) whether through scratching, falling, or rubbing off, not only can they infect other people, they can also reinfect (or further infect) the host they came from. For example, infected feet infest one's socks and shoes which further expose the feet to the fungus and its spores when worn again.
When visiting a doctor, the basic diagnosis procedure applies. This includes checking the patient's medical history and medical record for risk factors,[11] a medical interview during which the doctor asks questions (such as about itching and scratching), and a physical examination.[11] Athlete's foot can usually be diagnosed by visual inspection of the skin and by identifying less obvious symptoms such as itching of the affected area.
Athlete’s foot—the most prevalent foot fungus—thrives in warm, sweaty places like the insides of your athletic shoes, which is how it got its name. However, foot fungus can develop in multiple environments, natural and man-made, as long as there is lots of moisture where fungi can grow. These include shared areas at gyms or pools, soil and grass, or even shared items such as shoes, socks, or towels from household members who are infected.  
Athlete's foot occurs most often between the toes (interdigital), with the space between the fourth and fifth digits most commonly afflicted.[14][15][16] Cases of interdigital athlete's foot caused by Trichophyton rubrum may be symptomless, it may itch, or the skin between the toes may appear red or ulcerative (scaly, flaky, with soft and white if skin has been kept wet),[7][17] with or without itching. An acute ulcerative variant of interdigital athlete's foot caused by T. mentagrophytes is characterized by pain, maceration of the skin, erosions and fissuring of the skin, crusting, and an odor due to secondary bacterial infection.[13]
The Internet is filled with anecdotal information on how to cure toenail fungus using home remedies. Vinegar is a commonly recommended home remedy. Some people apply various oils such as tea tree oil, coconut oil, essential oils, and oil of cedar leaf (such as Vicks VapoRub) to their nails as well. The effectiveness of these home remedies is highly doubtful. Application of household bleach and hydrogen peroxide is also not recommended due to lack of evidence that these treatments work. These agents can also cause unwanted skin irritation. Thickened nails that have been affected by fungus can be difficult to trim. Using topical urea cream will soften the nail and make it easier to trim. These creams do not require a prescription.

Swelling and redness of the skin around the nail is called paronychia. This is an infection of the skin at the bottom of the nail (cuticle). If the infection is acute (has a rapid onset), it is usually caused by bacteria. It may respond to warm soaks but will often need to be drained by a doctor. A chronic paronychia occurs when a cuticle becomes inflamed or irritated over time. Sometimes, yeast will take advantage of the damaged skin and infect the area as well. Therapy begins with keeping the skin dry and out of water. If the problem continues, a physician should be consulted. Antibiotics are not often used but may be necessary in severe infection.
Fungus can infect the skin and nails of your feet. A fungal infection of the skin is also known as Athlete’s Foot, which causes itching, burning, and flaking. This infection can spread to the toenails if it’s not treated. Both types of foot fungus are extremely contagious, both in your own body as well as to other people through contact. Therefore, it’s essential to treat the infection and prevent its recurrence.
Oils such as olive oil and sunflower oil contain ozone gas. A 2011 study published in the Brazilian Journal of Microbiology, showed that small doses of this kind of ozone, applied over a short period, can eliminate fungus. A different study, conducted at the National Center for Scientific Research, Cuba, found that sunflower oil was more effective than the prescription drug Xolegel (ketoconazole).
Select shoes that fit right –  Choosing the correct footwear is a must if you want to avoid toenail fungus. Shoes should not touch your toenails at all. Don’t jam your feet into shoes that are too big either – this will cause you to jam your toenail into the front of the shoe causing damage. According to the American Academy of Physicians, the best shoes have a wide toe box.
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.

Healing time depends on the type of treatment used. Prevention of a new infection is important. Orthopaedic foot and ankle specialists recommend good foot hygiene with frequent changing of stockings and rotating pairs of shoes to allow them to completely dry between uses. Also, avoid going barefoot in locker rooms and around swimming pools. If you have a pedicure, make sure the nail salon uses sterilized instruments.

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.[37] As of 2013 research into laser treatment seems promising.[2] There is also ongoing development in photodynamic therapy, which uses laser or LED light to activate photosensitisers that eradicate fungi.[38]

Fungal nails (onychomycosis) may be caused by many species of fungi, but the most common is Trichophyton rubrum. Distal subungal onychomycosis starts as a discolored area at the nail's corner and slowly spread toward the cuticle. In proximal subungal onychomycosis, the infection starts at the cuticle and spreads toward the nail tip. Yeast onychomycosis is caused by Candida and may be the most common cause of fungal fingernail.
Nail fungus is usually harmless. But many people find discolored or thickened nails unpleasant to look at and want to get rid of the fungus as soon as possible. Fungal nail infections can also spread, and may infect other people. Regardless of the treatment you choose, it will take a while until the nail looks normal again. It’s especially important to be patient where toenails are concerned. It can take a year for a healthy big toenail to grow back. Nail fungus can sometimes be very persistent despite treatment. It can also come back after successful treatment.
You can also try itraconazole (Sporanox), which is usually prescribed with a dose of 200 mg a day for 12 weeks. Side effects can include nausea, rash, or liver enzyme abnormalities. It should not be used if you have liver issues. Sporanox also has interactions with over 170 different drugs such as Vicodin and Prograf. Check with your doctor to ensure any medication you are taking does not interfere with it.[7]
Topical agents such as amorolfine (Loceryl 5% nail lacquer; applied once or twice a week) and ciclopirox (Penlac 8% nail lacquer; applied daily) are usually prescribed for mild forms of the disease, but the treatment periods are long and their efficacy is somewhat limited due to poor nail plate penetration. These medications kill fungi by interfering with their cell membranes, which leads to their death.

Yeast onychomycosis: This type is caused by a yeast called Candida and not by the Trichophyton fungus named above. It is more common in fingernails and is a common cause of fungal fingernails. Patients may have associated paronychia (infection of the cuticle). Candida can cause yellow, brown, white, or thickened nails. Some people who have this infection also have yeast in their mouth or have a chronic paronychia (see above) that is also infected with yeast.
