Red or black nails due to a hematoma, or blood under the nail, usually occur from trauma (like whacking yourself on the thumb with a hammer). The discolored area will grow out with the nail and be trimmed off as you trim your nails. If you have a black spot under your nail that was not caused by trauma, you may want to see a dermatologist or a podiatrist if it involves a toenail to make sure it is not melanoma (a type of skin cancer associated with pigmented cells). A simple biopsy can rule out malignancy (cancer).
The possible side effects of itraconazole include headaches, dizziness, stomach and bowel problems, and rashes. Itraconazole can also interact with a number of other drugs. These include cholesterol-reducing and blood-sugar-lowering medications, as well as certain sleeping pills. It is therefore important to let your doctor know about any medication you take. Itraconazole is not an option for people with heart failure (cardiac insufficiency). It also isn’t suitable for women who are pregnant or breastfeeding.
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.

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]


Fungi that are already present in or on your body can cause nail infections. If you have come in contact with someone else who has a fungal infection, it may have spread to you. According to the American Academy of Dermatology (AAD), fungal infections affect toenails more commonly than fingernails because your toes are usually confined to your shoes, where they’re in a warm, moist environment.
Toenail fungus often begins as an infection in the skin called tinea pedis (also known as athlete’s foot). The fungus often starts under the nail fold at the end of the nail. Over time, it grows underneath the nail and causes changes to its appearance, such as a yellow or brownish discoloration. It can also cause thickening and deformity of the toenail. 
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.
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.
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.
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.
Topical antifungal agents can be used but are often ineffective. Oral terbinafine is considered to be the first-line treatment for confirmed onychomycosis; the treatment course is generally 6 weeks for fingernails and 12 weeks for toenails.9 Azoles can also be used. Surgical debridement or removal of the affected nail is also a consideration for cases that are resistant to antifungals, and laser treatments for onychomycosis appear to be a promising area for future study.10
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.

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.
Fungal nail infections can be difficult to treat. Talk with your doctor if self-care strategies and over-the-counter (nonprescription) products haven't helped. Treatment depends on the severity of your condition and the type of fungus causing it. It can take months to see results. And even if your nail condition improves, repeat infections are common.
Not all cases of OM require treatment with medication but if your doctor has confirmed you have OM and require treatment, they may prescribe an oral antifungal medication (terbinafine, itraconazole*) based on the type of fungus causing the infection. If you are unable to take oral antifungals or have a mild-to-moderate case of OM, your doctor may opt for a topical therapy (ciclopirox, efinaconazole*) that is applied to the affected nail(s) directly.
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).
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.  

Not all cases of OM require treatment with medication but if your doctor has confirmed you have OM and require treatment, they may prescribe an oral antifungal medication (terbinafine, itraconazole*) based on the type of fungus causing the infection.

Persistent fungal signs can show up slowly but last for years. Getting rid of toenail fungus can take some patience and requires time to fully heal. It can take several months until treatment is successful, but doing things the right way and getting rid of the underlying cause of nail fungus is the only thing that will keep the infection from coming back again.

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.

Recognize the signs. Before you can treat toenail fungus, you need to know what to look for. Nail fungus does not necessarily have consistent symptoms. The most common sign that you have nail fungus is tenderness or pain in the nail. Signs of a fungal infection include changes in your nail, such as color changes. The nail will usually get yellow or white streaks on the side of the nail. There is usually due to a buildup of debris under or around the nail, a crumbling and thickening of the outside edges of the nail, a loosening or lifting up of the nail, and nail brittleness.[3]


Efinaconazole (Jublia) is a medication that was approved in 2014. It is a topical (applied to the skin) antifungal used for the local treatment of toenail fungus due to two most common fungal species affecting nails (Trichophyton rubrum and Trichophyton mentagrophytes). Once-daily application is required for 48 weeks. The most common side effects of Jublia are ingrown toenails and application site dermatitis and pain.
Fungal nail infections don’t usually lead to serious long-term problems when properly treated, but they may be more serious in certain individuals. This can include people with diabetes or who have a weakened immune system and have trouble fighting off an infection. Even if there is no pain associated with the infection, it is important that you promptly visit your doctor for assessment if you see any abnormal nail changes.
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.
