Following effective treatment, recurrence is common (10–50%).[2] Nail fungus can be painful and cause permanent damage to nails. It may lead to other serious infections if the immune system is suppressed due to medication, diabetes or other conditions. The risk is most serious for people with diabetes and with immune systems weakened by leukemia or AIDS, or medication after organ transplant. Diabetics have vascular and nerve impairment, and are at risk of cellulitis, a potentially serious bacterial infection; any relatively minor injury to feet, including a nail fungal infection, can lead to more serious complications.[31] Infection of the bone is another rare complication.[6]
Ciclopirox (Penlac) topical solution 8% is a medical nail lacquer that has been approved to treat finger or toenail fungus that does not involve the white portion of the nail (lunula) in people with normal immune systems. In one study, ciclopirox got rid of the fungus 22% of the time. The medication is applied to affected nails once daily for up to one year. The lacquer must be wiped clean with alcohol once a week.
Anyone reporting immediate results or healing is either paid to post the review or doesn't have a true nail fungus. I have been using the solution for about 3 weeks now and can see progress/improvement, which is more than what I can say about other anti-fungal products I have tried. It appears to have contained the infection and the nail is growing it out.
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.
As both an antiseptic and fungicidal remedy, tea tree oil is a great remedy for onychomycosis.  First clean areas on and around the infection with rubbing alcohol then apply undiluted 100% pure tea tree oil (such as this Plant Therapy Tea Tree Oil) directly to the affected nails and let it soak in.  After about ten minutes, gently scrub the nail with a soft bristle toothbrush.  When applying tea tree oil directly to skin, consider mixing the oil one-to-one with an all-natural carrier, like olive or almond oil.  Repeat daily until the new healthy nail grows out completely, then continue treatment for two to three more weeks to prevent regrowth.
Scratching infected areas may also spread the fungus to the fingers and under the fingernails. If not washed away soon enough, it can infect the fingers and fingernails, growing in the skin and in the nails (not just underneath). After scratching, it can be spread to wherever the person touches, including other parts of the body and to one's environment. Scratching also causes infected skin scales to fall off into one's environment, leading to further possible spread.

Olive leaf extract is also a powerful detoxifier, so you may experience some discomfort when you first begin taking the supplement.  In this case, consider lowering your daily dose while your body sheds the bulk of its stored up toxins.  When you begin to feel revitalized, you can increase your intake to the recommended. Ready to try olive leaf extract? This Maximum Strength Olive Leaf Extract is the most popular supplement.  
Conventional treatment typically involves thoroughly washing the feet daily or twice daily, followed by the application of a topical medication. Because the outer skin layers are damaged and susceptible to reinfection, topical treatment generally continues until all layers of the skin are replaced, about 2–6 weeks after symptoms disappear. Keeping feet dry and practicing good hygiene (as described in the above section on prevention) is crucial for killing the fungus and preventing reinfection.

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.
Because fungal spores can remain viable for months in these environments, frequent exposure can increase the risk of infection (and re-infection). Fungal spores can be picked up in many ways – such as wearing shoes that harbour the organism, by walking barefoot in areas where the fungus is prevalent (especially public showers and locker rooms), by wearing wet shoes or socks for long periods, through previous injury to the toe or toenail that opens a path for easy entry of the fungus, or by wearing improperly-fitting shoes.
If the fungal nail infection is severe, tablets can be used in combination with nail polish or cream. For example, if the nail is very thick, urea cream can be used (in addition to taking tablets) to gradually remove or partially file off the affected nail. Combining these treatments may also be an option if there are large collections of fungi beneath the nail. Another option for severe fungal nail infections is professional medical footcare. If the nail is filed off, it’s important to ensure good hygiene and disinfect the area, because the removed nail tissue could contain infectious fungal spores.
For some people, a fungal infection of the nails can be difficult to cure and the first round of medication might not work. The nail infection can’t be considered cured until a new nail that’s free from infection has grown in. Although this indicates that the nail is no longer infected, it’s possible for the fungal infection to return. In severe cases, there may be permanent damage to your nail, and it may have to be removed.

Caprylic acid, one of the medium-chain fatty acids in coconut oil, has the ability to penetrate the durable cell wall of candida and other fungi.  Without its protective coating the cells of the fungus dissolve, effectively destroying the infection.  Apply a thin layer of coconut oil to infected areas and let it soak in for at least fifteen minutes.  Coconut oil is great for skin health, so there is no limit to how often you can use this treatment.  Just make sure you aren’t allergic to coconuts before applying this product to sensitive tissue.
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.
An imbalance of healthy micro-flora in the body can also be a big cause of fungal overgrowth like onychomycosis. Be sure to partner a good probiotic supplement with your choice of toenail fungus remedy.  Thriving, healthy gut bacteria hinder the growth and spread of parasitic fungi and other microbes by limiting their available living space.  Also, lactobacillus bacteria found in most probiotic supplements actually secrete a biproduct that is poisonous to Candida.  Just make sure that your supplement contains no sugar or artificial fillers that may inadvertently feed the unwanted fungus.
If the diagnosis is uncertain, direct microscopy of a potassium hydroxide preparation of a skin scraping (known as a KOH test) can confirm the diagnosis of athlete's foot and help rule out other possible causes, such as candidiasis, pitted keratolysis, erythrasma, contact dermatitis, eczema, or psoriasis.[13][23][27] Dermatophytes known to cause athlete's foot will demonstrate multiple septate branching hyphae on microscopy.[13]
The US Food and Drug Administration (FDA) has approved several medicines as topical applications to help treat foot and toenail fungus and prevent the fungus from recurring. PROFOOT anti-fungal products containing Tolnaftate 1% are clinically proven to cure and prevent fungal infections on skin around, adjacent to, and under nails, making it easy to treat fungal infections all day, every day, until they have cleared. ProClearz Fungal Shield is a safe and effective clear formula that dries quickly with no unpleasant odor. The 1 oz. bottle comes with a brush-on applicator designed to reach skin areas around and under nails.

Your physician may perform a simple test called a potassium hydroxide (KOH) preparation for microscopic fungal examination in the office or laboratory. This test can be used to confirm the presence of a fungal infection. This test is performed by using a microscope to examine small flakes of skin from the rash. Many dermatologists perform this test in their office with results available within minutes. Rarely, a small piece of skin may be removed and sent for biopsy or fungal culture to help confirm the diagnosis.

It may lead to other serious infections if the immune system is suppressed due to medication, diabetes or other conditions. The risk is most serious for people with diabetes and with immune systems weakened by leukemia or AIDS, or medication after organ transplant.

Athlete's foot, known medically as tinea pedis, is a common skin infection of the feet caused by fungus.[2] Signs and symptoms often include itching, scaling, cracking and redness.[3] In rare cases the skin may blister.[6] Athlete's foot fungus may infect any part of the foot, but most often grows between the toes.[3] The next most common area is the bottom of the foot.[6] The same fungus may also affect the nails or the hands.[4] It is a member of the group of diseases known as tinea.[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.

Athlete’s foot is one of the most common foot infections. It can be easily acquired, especially by people who often use communal showers and pools, such as those in college dorms or gyms. It grows in warm, damp places like public showers, locker rooms, and pools. It is also common with shoes that are too tight or socks or shoes that are damp. Athletes foot is contracted from getting pedicures with not properly sanitized equipment.
Fungal athlete's foot may cause a rash on one or both feet and even involve the hand. A "two feet and one hand" pattern is a very common presentation of athlete's foot, especially in men. Hand fungal infections are called tinea manuum. Fungal athlete's foot may also be seen along with ringworm of the groin (especially in men) or hand(s). It is helpful to examine the feet whenever there is a fungal groin rash called tinea cruris, or jock itch. It is important to treat all areas of fungal infection at one time to avoid reinfection. Simply treating the soles and ignoring the concurrent fungal infection of toenails may result in recurrences of athlete's foot.
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.
