Pseudomonas Nail Infection – Causes, Symptoms & Best Treatment

Pseudomonas Nail Infection: Pseudomonas nails usually appear as green or dark green spots underneath the fingernails & toenails. Make 100% Sure! Look:

• Yellow & green toenail fungus can be improved with a few simple treatment changes.
• We are foot doctors & we see this problem get better almost every day.
• The goal is to solve this problem without medication or surgery if at all possible.

So, let’s GO!

Pseudomonas Nail Infection Overview

• Pseudomonas is a bacterial infection, and it does differ from toenail fungus.
• Pseudomonas aeruginosa is a bacteria that is not the most aggressive infection.
• If there is redness or pain, this may become cellulitis.
• Be careful and seek care from a podiatrist if worried!

What Is a Pseudomonas Nail Infection:

Pseudomonas nail infection can take place between the nail plate & the nail bed. It results in a green-looking toenail or fingernail.

• Pseudomonas is not a mold as it is reputed to be in the nail tech industry, but a bacteria!
• It is frequently referred to as “greenies” or “green nails” by the nail tech industry.
• The greenish-black color is caused by a bacteria that loves oxygen and water called Pseudomonas aeruginosa.
• It is frequently acquired by getting dirt under your nails from pond water, hot tubs, and pools.
• Nail irritation combined with increased moisture leads to it colonizing your fingertips.

Causes:

How Does Pseudomonas Nail Infection Occur: Two things need to occur before a Pseudomonas nail infection occurs.

1. There must be microscopic cracks or injury underneath your fingernail or toenails:

• This usually occurs due to scrapping with your nails or damaging them microscopically.
• There could be nail plate separation from the nail bed (onycholysis).
• There could be paronychia (inflammation of the nail border).
• This allows an entry point for the bacteria.
• Without this entry point, the bacteria could never get underneath the nail plate.

2. The Pseudomonas bacteria then get underneath the nail & replicates:

• Once these cracks occur, the Pseudomonas bacteria can burrow itself underneath the toenail or fingernail.
• The bacteria are then safe underneath the toenail and can grow.
• Antibiotics or topical treatment may be needed to resolve this condition.

Who is at risk for Pseudomonas infection?

• The risk of Pseudomonas goes up with dirt.
• Those who have cracks underneath the fingernails & toenails.
• There could be nail plate separation from the nail bed (onycholysis).
• There could be paronychia (inflammation of the nail border).
• Using artificial nails, nail polish, or nail polish remover.

Artificial Nails Increase The Chances:

• Artificial nails, toenail polish & toenail polish remover, increase stress on your nail plate.
• This can give the bacteria an advantage in getting underneath the nail and growing.
• Consider going natural until the bacteria is resolved!

Pseudomonas Nail Infection Treatment:

If you ever have any worries, make sure to see your podiatrist for antibiotics.

• These include both oral & topical!

Home Remedy: Vinegar is very effective in dealing with toenail fungus, but the principles hold for pseudomonas infection! The beauty is the pseudomonas infection will not destroy your nail. Once it is killed, the nail will look normal again.

A. Apple vinegar soaks for Pseudomonas

Pros:

• Easy to use method.

• Very cheap and readily available at home.

• 85% success rate.

Cons:

• Can irritate the skin in some people.

• It can get annoying to soak your feet every day.

The success rate can be 85%+ after 4 weeks of use!

Why Does It Work?

• A Michigan State University (MSU) study shows that Vinegar has anti-microbial properties.
• This study focused on fungal toenails, but pseudomonas is much more superficial and easier to treat than toenail fungus.
• Apple Cider Vinegar provides an inhospitable acidic environment for the fungus & the bacteria.
• It is a fungicidal chemical. This means that it kills the bacteria rather than just preventing its growth.
• It is widespread to hear people say they feel immediately better after using this for a short time!

Toenail Fungus Is More Likely:

Toenail fungus is frequently greenish yellow & is very frequently involved with nail discoloration. If the above does not sound like your situation, consider toenail fungus as well.

• Toenail fungus is associated with 80% of all toenail problems.
• It usually manifests as thick yellow toenails, but there can be brown and black marks as well.

Pseudomonas Nail Infection Treatment – FAQs

Can I put nail polish over pseudomonas? It would not be a good idea to put nail polish over a pseudomonas nail infection. This can trap moisture and allow more bacteria to grow. What is a Pseudomonas nail infection? A Pseudomonas nail infection is a bacterial infection that often causes green or dark discoloration of the nail, commonly known as green nail syndrome. It develops in moist environments or under artificial nails. What are the symptoms of a Pseudomonas nail infection? Symptoms may include green, black, or yellow nail discoloration, foul odor, nail lifting, and tenderness around the nail. How is Pseudomonas nail infection treated? Treatment typically includes professional nail cleaning, topical or prescription medication, moisture control, and guidance to prevent reinfection. Severe cases may require more advanced care. Can a Pseudomonas nail infection heal on its own? In mild cases, symptoms may improve, but without proper treatment the infection often persists or worsens. Podiatric care helps fully eliminate the bacteria and protect the nail. When should I see a podiatrist for small toe discomfort?

If the pain persists for more than a week, worsens with activity, interferes with walking, or shows signs of deformity or discoloration, it’s best to consult a foot and ankle specialist for a proper diagnosis and treatment plan.

Is Pseudomonas nail infection contagious? The infection is not usually contagious through casual contact, but sharing nail tools or maintaining damp conditions can increase risk. When should I see a podiatrist for green nail syndrome?

You should see a podiatrist if nail discoloration persists, spreads, causes odor or pain, or if you have diabetes or circulation issues.
