Fungal infections of the nails, called onychomycosis, are pretty common. While you’re more likely to get a fungal infection in your toenails, your fingernails can be affected, too.
But what if your nail turns green? This article is about “greenies,” or chloronychia. The interesting thing about chloronychia is that it’s not actually a fungal infection. Instead, the greenish color is caused by a bacterial infection, usually Pseudomonas aeruginosa.
So, if you’re wondering how to get rid of green fingernail fungus, you’re actually dealing with a bacterial infection, not a fungal one. This article will tell you how to identify, treat, and prevent green fingernail infections.
Understanding Chloronychia: The “Green Fingernail”
So, you’ve got a green fingernail. What’s going on?
What is Chloronychia?
That green color is a sign of chloronychia. It’s an infection that’s often mistaken for a fungal infection, but it’s actually a bacterial infection.
Usually, the culprit is Pseudomonas aeruginosa, a type of bacteria. This bacteria makes pigments that stain the nail green.
Risk Factors and Causes
How do you get this green fingernail thing, anyway?
Usually, moisture and trauma play a role. If your hands are repeatedly exposed to water or you experience minor injuries to your nail, you can create an environment where Pseudomonas can thrive.
Artificial nails and acrylics are also common culprits. They can trap moisture and create the perfect breeding ground for bacteria.
Underlying nail conditions, like onycholysis (when the nail separates from the nail bed), can also increase the risk of developing chloronychia.
Identifying a Green Fingernail Infection
So, you think you might have a green fingernail infection? Here’s what to look for:
- Green discoloration: The most obvious sign is a green, blue-green, or even brownish-green tint to your nail. It might look like a bruise that won’t go away.
- Nail plate changes: Sometimes, the nail might get soft or thick. It really just depends.
- Onycholysis (nail separation): The nail might start to detach from the nail bed. You’ll see it lifting up, creating a space underneath.
- Absence of typical fungal nail infection symptoms: This is key! If your nail is brittle, crumbly, or has a bad odor, you’re more likely dealing with a fungal infection. Green nail syndrome, also known as Chloronychia, typically doesn’t cause these symptoms.
Basically, if you see green, think bacteria, not fungus (at least at first). If you’re unsure, it’s always best to see a doctor or dermatologist to get a proper diagnosis.
Treatment options for green fingernail infections
If you think you may have green nail syndrome, you’ll want to see a doctor for a diagnosis.
Once you have a diagnosis, you can begin treatment. Depending on the severity of the infection, there are several approaches you can try.
Topical treatments
For mild cases, your doctor may recommend topical antibacterial solutions and ointments. Some common topical antibiotics are polymyxin B and bacitracin.
Another topical treatment involves antiseptic soaks. You can try diluted vinegar or bleach soaks to kill the bacteria, similar to foot soak solutions. If you choose this option, be sure to follow dilution instructions carefully.
Oral antibiotics
Oral antibiotics are usually reserved for severe or persistent cases of green nail syndrome. Your doctor may prescribe an antibiotic like ciprofloxacin.
Nail removal
In very severe cases where the infection doesn’t respond to other treatments, your doctor may recommend removing the nail.
Addressing underlying causes
To prevent green nail syndrome from recurring, it’s important to address any underlying causes, such as onycholysis or other nail conditions. Be sure to keep your nails clean and dry, and avoid prolonged exposure to moisture.
Home care and prevention strategies
Once you’ve dealt with the infection, it’s a good idea to make some changes to your routine to prevent future infections.
Keep nails clean and dry
Wash your hands thoroughly and dry them well. It sounds simple, but washing your hands often is one of the best ways to prevent the spread of germs. Drying your hands completely is just as important. Bacteria love moisture.
Avoid prolonged exposure to moisture. Wear gloves when you’re doing dishes or other wet work.
Practice proper nail care
Trim your nails short and straight across. This helps prevent moisture and bacteria from getting trapped under the nail.
Avoid trauma to the nail. Be careful when you’re giving yourself a manicure. Also, avoid biting or picking at your nails.
Disinfect nail tools
It’s important to clean and disinfect your nail tools regularly. Use alcohol or bleach solutions to disinfect nail clippers, files, and other tools.
Avoid artificial nails
Artificial nails aren’t a great idea if you are prone to nail infections. The problem is that they can trap moisture and create a breeding ground for bacteria.
If you love the look of artificial nails, consider using regular nail polish instead. Or take breaks from artificial nails to allow your natural nail to breathe.
Use antifungal and antibacterial products
You can use these products as a preventative measure, especially after you’ve been exposed to water or in high-risk environments, such as public pools.
Frequently Asked Questions
What kills fingernail fungus the fastest?
Unfortunately, there’s no magic bullet for quickly eradicating fingernail fungus. Topical and oral antifungal medications prescribed by a doctor are the most effective, but they often require weeks or even months of consistent use to see results. The fastest approach usually involves a combination of prescription treatment and diligent nail care.
Does vinegar get rid of nail fungus?
Vinegar, particularly apple cider vinegar, is often touted as a home remedy for nail fungus. While some people find it helpful in slowing fungal growth due to its acidic properties, there’s limited scientific evidence to support its effectiveness in completely eliminating the infection. It may be worth trying as a complementary treatment alongside medical interventions.
Is green nail fungus contagious?
Green nail syndrome, or chloronychia, caused by Pseudomonas bacteria, isn’t highly contagious like typical fungal infections. It usually develops when moisture gets trapped under the nail, creating a breeding ground for the bacteria. However, it’s still wise to avoid sharing nail clippers or other personal items to prevent potential spread.
What causes green fungus under acrylic nail?
Green discoloration under acrylic nails is typically caused by a Pseudomonas bacterial infection. This happens when moisture becomes trapped between the natural nail and the acrylic, providing a dark, damp environment where the bacteria thrive. Improper application or lifting of the acrylic nail can increase the risk.
What kills green fingernail fungus?
Green nail syndrome caused by Pseudomonas bacteria is best treated with topical antibiotics or antiseptic solutions. Your doctor may prescribe a specific medication or recommend soaking the affected nail in a diluted bleach solution. Keeping the area dry and avoiding artificial nails until the infection clears is also crucial.
Final Thoughts
Remember, green nails aren’t caused by a fungus. They’re caused by a bacterial infection called chloronychia. Getting the right diagnosis is the first step toward getting better.
One of the best ways to avoid chloronychia is to practice good hygiene. Keep your nails clean, dry, and trimmed. Don’t bite your nails, and avoid wearing artificial nails for long periods.
If you have a severe case of chloronychia, or if your infection doesn’t get better with home treatment, you should see a doctor. They can prescribe antibiotics to help clear up the infection.
Even after your infection is gone, it’s important to continue to take steps to prevent it from coming back. Keep your nails clean and dry, and avoid activities that could damage your nails.
