Don’t Let Nail Discoloration Get You Down!
Most of us don’t think much about our toenails—until something changes. If you’ve noticed yellowing, thickening, dark streaks, or other forms of discoloration in your toenails, you might be wondering if it’s harmless or something more serious. At FitFeet, with offices in Merrick, Williamsburg, and Brighton Beach (Brooklyn), we help patients every day who are concerned about changes in their toenails. Sometimes it’s nothing to worry about—but sometimes, it’s a sign that professional care is needed.
So how do you know when it’s time to see a podiatrist for nail discoloration? Here’s what to look for, and how our expert team can help.
What Causes Nail Discoloration?
Discolored toenails can happen for a variety of reasons, ranging from simple cosmetic issues to more serious medical concerns. Common causes include:
- Fungal infections (onychomycosis), which often cause yellow, brown, or white discoloration
- Injury or trauma, such as stubbing your toe or dropping something on it
- Underlying health issues, like diabetes, psoriasis, or poor circulation
- Dark streaks, which can be harmless bruising or, in rare cases, a sign of melanoma
- Nail polish or harsh chemicals, which can stain the nail temporarily
- Thickened nails, often due to long-standing fungal infection or damage
If the discoloration is new, worsening, or accompanied by pain or nail deformity, it’s a good idea to get it checked by a foot specialist.
When to See a Podiatrist in Merrick, Williamsburg, or Brighton Beach
While some nail changes may resolve on their own, others require medical evaluation. You should schedule a visit with a podiatrist at any of our three convenient FitFeet locations—Merrick, Williamsburg, or Brighton Beach in Brooklyn—if you notice:
- Yellow, white, or brown discoloration that doesn’t go away
- A black or dark streak on the nail
- Crumbling, thickened, or misshapen toenails
- Pain, swelling, or signs of infection near the nail
- Nail separation from the nail bed
- A history of diabetes or poor circulation along with nail changes
Fungal infections are one of the most common causes of discolored toenails. While they may start small, they can spread and become difficult to treat if left alone. The earlier you address the problem, the more effective your treatment will be.
Don’t Wait to Treat Toenail Fungus
If your nail is turning yellow, white, or brown and becoming thick or brittle, it’s likely a fungal infection. These infections are stubborn and often won’t respond to drugstore creams or home remedies.
At FitFeet in Merrick, Williamsburg, and Brooklyn, we offer several effective treatment options for fungal nails, including:
- Fotona laser treatment, which targets the infection under the nail without harming surrounding tissue
- Topical and oral antifungal medications, depending on the severity
- Nail debridement to reduce thickness and help treatment penetrate deeper
- Preventive counseling and hygiene tips to avoid recurrence

Laser therapy is a popular option for patients who prefer to avoid systemic medication. It’s painless, quick, and available at all three of our FitFeet locations.
What If It’s Not Fungus?
Not all discoloration is caused by infection. If you’ve had a recent injury—such as stubbing your toe or dropping something heavy—you may develop a bruise or blood spot under the nail. This often appears as a black or purple discoloration, and in many cases, it will grow out over time. However, if the discoloration doesn’t change or the nail becomes painful or lifts from the bed, we recommend an exam.
In more serious cases, a persistent dark streak that appears without injury could be a sign of subungual melanoma, a rare but serious form of skin cancer that develops under the nail. This is why early evaluation by a podiatrist is crucial, especially if the streak changes shape, darkens, or appears on a single toe.
Nail Discoloration and Chronic Conditions
If you have diabetes, poor circulation, or a weakened immune system, even mild nail changes can lead to bigger problems. People with diabetes are at higher risk of developing infections, ulcers, and delayed healing, especially in the feet.
At FitFeet, we take diabetic foot care seriously and help patients monitor their foot health—including nails—at all stages. We offer regular foot exams at all three of our offices: Merrick, Williamsburg, and Brighton Beach.

How We Diagnose the Cause of Nail Discoloration
When you visit FitFeet, we’ll start with a thorough exam that may include:
- A review of your health and foot history
- Visual inspection of the nail and surrounding skin
- Possible nail biopsy or sample to confirm fungal infection
- Evaluation of gait or foot structure if trauma is involved
- Imaging if deeper injury is suspected
Our goal is to get to the root of the problem, so we can offer the most effective treatment and long-term solution.
Treatment Options at FitFeet Merrick, Williamsburg, and Brooklyn
Depending on the cause of your nail discoloration, we’ll tailor your treatment plan to your individual needs. This may include:
- Laser therapy for fungal nails
- Antifungal medications, topical or oral
- Debridement (nail thinning or trimming)
- Surgical removal of the nail, only when necessary
- Wound care and infection management, if present
- Monitoring for recurrence, especially in chronic cases
We’ll also provide guidance on how to care for your nails at home, what to avoid, and how to reduce your risk of reinfection or injury.
