Unfortunately, athlete’s foot is highly contagious and the fungus can easily spread to the toes and toenails, causing infections. There are more than three million cases of toenail fungus in the US every year. Not all toenail infections are from athlete’s foot or even from a fungus; some are caused by yeast or mold. These are much harder to cure than fungal infections.

If you observe any abnormal nail changes it is important to visit your doctor for prompt assessment. In addition to being cosmetically unappealing, OM can also lead to more serious complications, including the possible loss of your nail, bacterial infections, or cellulitis. Speak with your healthcare provider to determine what the best treatment plan is for you.
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.
Once it takes hold, the bacteria and yeast thrive off of sugar molecules entering the digestive tract through the foods you eat. That’s exactly why you need to eliminate the underlying cause, which is likely stemming from your diet (and possibly also your lifestyle to some degree). This will help ultimately restore your body’s pH balance, improve your immune function and boost the presence of good bacteria in your gut.
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.

Technically called “onychomycosis”, fungal infection of the nail plate (the hard outer nail) or nail bed (that lies under the hard nail) will most often appear as yellowish, white, black or green discolouration of the nail. The infected nail may also appear thickened or brittle. In severe cases, from long-term infection (where all the tissues of the nail have been infected), the infected nail may break up and fall off.
Globally, fungal infections affect about 15% of the population and affects one out of five adults.[2][21] Athlete's foot is common in individuals who wear unventilated (occlusive) footwear, such as rubber boots or vinyl shoes.[21][23] Countries and regions where going barefoot is more common experience much lower rates of athlete's foot than do populations which habitually wear shoes; as a result, the disease has been called "a penalty of civilization".[35] Studies have demonstrated that men are infected 2–4 times more often than women.[2]
The term "ringworm" or "ringworms" refers to fungal infections that are on the surface of the skin. A physical examination of the affected skin, evaluation of skin scrapings under the microscope, and culture tests can help doctors make the appropriate distinctions. A proper diagnosis is essential to successful treatment. Among the different types of ringworm are the following: tinea barbae, tinea capitis, tinea corporis, tinea cruris, tinea faciei, tinea manus, tinea pedis, and tinea unguium.

Keeping socks and shoes clean (using bleach in the wash) is one way to prevent fungi from taking hold and spreading. Avoiding the sharing of boots and shoes is another way to prevent transmission. Athlete's foot can be transmitted by sharing footwear with an infected person. Hand-me-downs and purchasing used shoes are other forms of shoe-sharing. Not sharing also applies to towels, because, though less common, fungi can be passed along on towels, especially damp ones.
Readily available over-the-counter treatments work well for most nail-bed infections, especially early cases. An advanced toenail fungus infection may require a podiatrist’s intervention. To counteract a serious infection, medical professionals may utilize prescription topical medications, oral medications, and even laser therapy.  Some cases best respond to combination therapy.
Dermatologists specialize in the treatment of skin disorders, including athlete's foot. You may find a board-certified dermatologist through http://www.aad.org. Additionally, family medicine physicians, internal medicine physicians, pediatricians, podiatrists (foot doctors), and other practitioners may also treat this common infection. Most primary care physicians can treat athlete's foot successfully.
Treatment options during pregnancy may include dilute vinegar soaks or sprays (roughly one part white household vinegar to four parts water) and Lotrimin cream twice a day for two to three weeks to the soles. Antifungal pills are generally not recommended during pregnancy because of the potential side effects and possible fetal harm. Always check with your OB/GYN before using any medication or treatment during pregnancy.
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.

Apply Vick's VapoRub. You can get over the counter vapor rub from Vick's to help your fungus. A study showed that daily application of Vick's VapoRub for 48 weeks can be as effective as topical treatment options such as Ciclopirox 8% for nail fungus.[12] To treat nail fungus with Vick's VapoRub, first make sure your nail is clean and dry. Apply a small amount of Vick's VapoRub on the affected area daily with your finger or a cotton swab, preferably at night. Continue treatment for up to 48 weeks.
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]
Fungal infection occurs when the organism invades through an opening in the nail, meaning fungi will usually attack nails that are already damaged. After infection occurs, the growth of the fungi leads to mild inflammation, which causes the nail to thicken and the nail plate to detach from the nail bed. The space underneath the nail can then serve as a reservoir for bacteria and moulds, which can cause the nail to become discoloured.
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]
A number of different types of fungus can cause onychomycosis including dermatophytes and Fusarium.[3] Risk factors include athlete's foot, other nail diseases, exposure to someone with the condition, peripheral vascular disease, and poor immune function.[3] The diagnosis is generally suspected based on the appearance and confirmed by laboratory testing.[2]
Other causative pathogens include Candida and nondermatophytic molds, in particular members of the mold genus Scytalidium (name recently changed to Neoscytalidium), Scopulariopsis, and Aspergillus. Candida species mainly cause fingernail onychomycosis in people whose hands are often submerged in water. Scytalidium mainly affects people in the tropics, though it persists if they later move to areas of temperate climate.
Garlic has antifungal properties useful to foot fungus treatment, thanks to its compounds such as allicin and ajoene. These natural compounds work to treat the toenail fungus. Mix crushed up garlic or garlic oil with white vinegar. Apply the mixture on and around the infected area and then cover it with a bandage. Leave the bandage on for a few hours. Repeat daily until the toenail fungus clears. Plus, learn about the other signs of disease your feet can reveal.

For more severe cases, oral antifungal medications might be required. These include fluconazole (an antifungal agent also commonly used to treat thrush), terbinafine (a broad-spectrum antifungal) and griseofulvin (usually used for skin infections). The latter is a very old drug and carries the risk of causing damage to the liver. Terbinafine is most effective and therefore is the preferred oral treatment. A 12-week course cures 70-80% of cases by causing the fungi’s cells to leak and die. It can, however, cause gastrointestinal side effects and depression.


Walking barefoot in public places: Sure, taking your shoes off may feel great but it can also lead to toenail fungus. Toenail fungus starts when moisture gets trapped under the nail. This can easily happen when you walk barefoot.It is also easy to pick up toenail fungus from walking in public places as fungus can survive for up to 6 months on surfaces. The most common public places where you can pick up toenail fungus include swimming pools and public showers. Protect yourself by wearing sandals in public pool areas and public showers.
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.

Patience is key, as treatment duration varies from 2-3 months for oral treatments to up to 12 months for topical treatment. Because the nails take a long time to grow (6 months for fingernails and 12-18 months for toenails), it will take some time for the infection to resolve and the nail appearance to improve, regardless of the type of treatment used. Sometimes treatment may not be successful and your doctor may prescribe a different medication.
I can tell you my own mother struggled with toenail fungus on her big toe for over 10 years, and the reason why she originally got it and then continued to struggle with this fungus was the chemotherapy she went through when diagnosed with breast cancer years ago. After going through chemo, she had systemic yeast and candida issues and then developed the toenail fungus. The exact treatment I detail below is what we used with her to successfully erase her fungus.

Ringworm, also called tinea corporis, is not a worm, but a fungal infection of the skin. It can appear anywhere on the body and it looks like a circular, red, flat sore. It is often accompanied by scaly skin. The outer part of the sore can be raised while the skin in the middle appears normal. Ringworm can be unsightly, but it is usually not a serious condition.


Readily available over-the-counter treatments work well for most nail-bed infections, especially early cases. An advanced toenail fungus infection may require a podiatrist’s intervention. To counteract a serious infection, medical professionals may utilize prescription topical medications, oral medications, and even laser therapy.  Some cases best respond to combination therapy.
One of the best remedies for toenail fungus, apple cider vinegar can be used topically, internally, or both. Mix one part ACV and one part Epsom salts with six parts hot water.  Let the water cool so that it is still warm to the touch, but not so hot as to be damaging to your skin.  Soak feet up to twice daily for at least thirty minutes to kill fungus.  Mix two tablespoons of organic apple cider vinegar with eight ounces of warm water and add a teaspoon of honey to sweeten the beverage.
Apply Vick's VapoRub. You can get over the counter vapor rub from Vick's to help your fungus. A study showed that daily application of Vick's VapoRub for 48 weeks can be as effective as topical treatment options such as Ciclopirox 8% for nail fungus.[12] To treat nail fungus with Vick's VapoRub, first make sure your nail is clean and dry. Apply a small amount of Vick's VapoRub on the affected area daily with your finger or a cotton swab, preferably at night. Continue treatment for up to 48 weeks.

If common remedies do not offer relief within three to four months of consistent use, or if the discomfort worsens, contact your doctor. Extreme infections may require the temporary surgical removal of the nail. A replacement nail will usually grow. As the new nail regrows, it is good practice to treat it with an antifungal cream to prevent reinfection.
Mouthwash kills bacteria and germs in your mouth, so why not use it to kill bacteria and germs on your feet? Its antiseptic properties work to keep away harmful bacteria and fungi. Combine equal parts white vinegar and mouthwash and soak the infected area for 30 minutes, then scrub the toenail area gently. Repeat once or twice daily until the foot fungus clears. Make sure you know these home remedies for athlete’s foot.
There are several doctors who can provide nail fungus treatment. Your primary care provider, a dermatologist, or a podiatrist can treat nail fungus. Any one of these doctors can provide proper diagnosis and prescribe medications specific to fungal infection. A podiatrist or dermatologist may shave the top layer of the nail off or even remove part of the nail.
Before taking action and finding the best nail fungus treatment for you, it is important to note that toenail fungus and skin fungus, such as athlete’s foot, often manifest together. For the best results, both should be treated at the same time to prevent an ongoing infection. You can recognize athlete’s foot by the dry, scaling, peeling skin on the bottom of the feet. Your feet may also itch, or exude a noticeable odor.
Physical exam alone has been shown to be an unreliable method of diagnosing fungal nails. There are many conditions that can make nails look damaged, so even doctors have a difficult time. In fact, studies have found that only about 50% of cases of abnormal nail appearance were caused by fungus. Therefore, laboratory testing is almost always indicated. Some insurance companies may even ask for a laboratory test confirmation of the diagnosis in order for antifungal medicine to be covered. A nail sample is obtained either by clipping the toenail or by drilling a hole in the nail. That piece of nail is sent to a lab where it can by stained, cultured, or tested by PCR (to identify the genetic material of the organisms) to identify the presence of fungus. Staining and culturing can take up to six weeks to get a result, but PCR to identify the fungal genetic material, if available, can be done in about one day. However, this test is not widely used due to its high cost. If a negative biopsy result is accompanied by high clinical suspicion, such as nails that are ragged, discolored, thickened, and crumbly, it warrants a repeat test due to the prevalence of false-negative results in these tests.
