Leaving toenail fungus untreated causes the nail to become thickened, brittle, discolored, and crumbly, leading to pain, difficulty walking, and potential separation from the nail bed, with risks of spreading to other nails, the skin (athlete's foot), or causing more serious bacterial infections like cellulitis, especially for those with diabetes or weakened immune systems, and can result in permanent nail damage.
Will a toenail fungal infection go away by itself? Unfortunately, toenail fungus won't go away without treatment. If you leave the infection untreated, the fungus will continue to spread until the nail is permanently destroyed.
A severe case of nail fungus can be painful and may cause permanent damage to your nails. And it may lead to other serious infections that spread beyond your feet if you have a suppressed immune system due to medication, diabetes or other conditions.
Onychomycosis or infected nails are most often caused by a type of parasitic fungi called dermatophyte fungi. As the infection progresses, the affected nail can become itchy and/or slightly painful.
How is pediatric onychomycosis treated? Topical antifungal creams, lotions, gels, and lacquers may be used, however, it is difficult for them to penetrate the nail. Oral medicines like itraconazole, terbinafine, and fluconazole are used, and may require monitoring with blood tests.
Additionally, biotin deficiency can increase the risk of fungal nail infections and subsequent nail plate discoloration. Changes in nail shape and surface.
Toenail fungus is tough to kill permanently, but the most effective treatments are prescription oral antifungal drugs (like terbinafine), followed by strong topical antifungals, often used together, while laser therapy and sometimes nail removal (surgery) are options for persistent cases, though home remedies rarely provide a complete cure and professional help is key for lasting success.
Fungal infections usually appear as circular, scaly, or itchy patches. They often have well-defined borders and may resemble a ring, especially in the case of ringworm. The skin can look red and irritated, and sometimes peels or flakes.
Keratin granules are areas of damage to the top layers of the nail. They show up as small, chalky white spots or rough patches and happen when nail polish, especially if left on too long, dries out and weakens the surface of the nail.
Fungal nail infection: What else might it be?
You may have a higher risk of getting toenail fungus if you have: Athlete's foot (tinea pedis). Diabetes. Hyperhidrosis (a disorder that makes you sweat a lot).
People with toenail fungus are at a higher risk of developing other fungal infections—including those that affect the heart. Toenail fungus can sneak up on you—especially if you're immunocompromised or have preexisting health conditions.
While rare, severe cases of toenail fungus can potentially lead to systemic infection, especially in individuals with compromised immune systems. In such cases, the fungus may enter the bloodstream and spread to other parts of the body, including vital organs.
Even a mild infection like this can snowball into something more serious, like cellulitis, a severe bacterial skin infection. Another problem is that untreated fungus eventually can spread to either neighboring toenails or to the skin of your foot, causing athlete's foot.
If your nail gets brittle and breaks easily, it's a sign the fungal infection is changing the composition of the nail. If it becomes soft and chalky and starts to crumble away, the infection is starting to become severe.
While a skin or nail fungus can easily spread from one body part to another or from one person to another via contact, it's extremely rare for a toenail fungus itself to spread internally.
Can You Scrape Out Toenail Fungus? No. You may be able to scrape a bit off the top of or from under your nails, but that won't cure the infection.
Antifungal medicines can kill a fungus. Or they may stop it from multiplying or growing. There are several classes of antifungal medications and different types of medicines. Your healthcare provider will select the best prescription medicine.
Symptoms of Fungal Infections
“Each evening, patients go to a bathroom or other place with a vinegar-resistant floor, don old cotton socks, pour a few spoons of plain or apple-cider vinegar and a few spoons of water over the toes, and sit and read for 10-15 minutes. They then doff the socks, apply topical antifungals, and go to bed.
Eating foods and oils that improve your gut health is a great way to ward off toenail fungus. Doing so also improves your immune system. Try to eat fermented foods like yogurt, sauerkraut, kefir, garlic, onions, and asparagus.
Podiatrists recommend a multi-pronged approach for toenail fungus, often starting with prescription oral antifungals (like terbinafine) for moderate to severe cases due to their high success rates, though requiring liver monitoring. They also use topical antifungal lacquers, often combined with professional nail debridement (thinning) for better penetration, alongside laser therapy (PACT) and strict foot hygiene (drying, airing shoes, antifungal sprays) to prevent recurrence, as single treatments often fail.
