Comprehensive Care for Nail Disorders

Precision Treatment for Hands and Feet That Look and Feel Better

Your nails can reflect what’s happening locally and sometimes what’s happening systematically. While nail issues are easier to ignore, others can be more worrying, especially when they start interfering with everyday life.

At Connolly Dermatology, nail disorder treatment starts with precision. We focus on confirming diagnoses, blending medical dermatology expertise with careful procedural care to build a comprehensive plan tailored to your needs.

You deserve nails that look healthy and feel comfortable without guessing your way through home remedies or product cycles that don’t match the problem. When we treat nail disorders, we work on reducing recurrence and improving the nail plate to improve your comfort levels and help you feel more put-together from the tips of your fingers to the end of your toes.

What Are Nail Disorders?

When Thickening, Lifting, or Discoloration Needs Medical Attention

Nail disorders are conditions that can affect different parts of the finger tip:

• The nail plate (the hard nail you see)
• The nail bed (skin beneath the nail)
• The nail matrix (the part where the nail grows)
• Surrounding folds of skin at the tip of the finger

Because nails grow slowly, changes can appear gradually. These changes aren’t always about appearance, as they can show up as thickening, brittleness, lifting, ridges, pitting, discoloration, or tenderness along the edges.

What makes these concerns tricky is that different problems can look almost identical at first. A fungal infection can mimic psoriasis. Trauma from tight shoes can resemble chronic inflammation. Even frequent manicures or gel removal can leave a nail looking damaged in a way that’s easy to misread. That’s why a correct diagnosis matters, as nails don’t respond well to trial-and-error, and the wrong approach can drag the issue out for months.

Common Causes of Nail Disorders

Most concerns fall into a few major categories:

• Infections: Fungal infections are common, especially in toenails, and often start alongside athlete’s foot. Bacterial infection can develop when the skin around the nail is inflamed or broken.
• Repeated Trauma and Pressure: Tight shoes, long-distance walking or running, and impact to the toes can thicken or distort the nail over time. For fingernails, repetitive wet work, such as picking and tapping, as well as tool use, can cause persistent splitting or roughness.
• Inflammatory Skin Conditions: Psoriasis is a leading cause of pitting, lifting, and crumbly texture. Eczema and chronic dermatitis can also affect the surrounding skin and nail growth.
• Irritants and Allergies: Harsh solvents, frequent acetone use, and certain nail products can trigger inflammation in the nail folds, weakening the nail surface.
• Structural Issues: Ingrown nails often develop from trimming habits, shoe pressure, or the natural curve of the nail.

Certain health factors can also raise risk or slow recovery, including diabetes, circulation issues, immune suppression, excessive sweating, and a history of recurrent athlete’s foot.

When to See a Dermatologist

If you’re wondering whether it’s worth getting checked by a specialist, use function and progression as your guide. A good rule to follow is: if the problem is persistent, spreading, painful, or changing quickly, it’s time to book an evaluation. 

Make an appointment if you notice:

• Pain, swelling, or tenderness, especially along the sides of a toe
• Drainage, crusting, or a foul smell, which can signal infection
• Lifting or separation of the nail from the skin underneath
• Thickening or crumbling that makes trimming difficult
• Discoloration that’s new or worsening, especially if it appears in a single nail
• A “different” nail that doesn’t match the others and isn’t improving over time
• Recurrence after OTC treatments, or symptoms that keep returning

Nails grow slowly, especially in the toes, which means that waiting for them to grow out can result in months of worsening thickness, discomfort, or reinfection. A dermatologist can confirm what’s actually driving the changes to ensure focused, targeted strategies that are far more likely to work.

From Fungus To Psoriasis: Why Similar-Looking Problems Need Different Care

Changes in the nails can look deceptively similar. A thick, yellow toenail may be a sign of fungus, or it may be caused by repeated pressure from footwear. Lifting can be caused by infection, psoriasis, or irritation from products. 

That’s why we group these concerns by what’s driving the change: infection, inflammation, structure, or trauma. Once the underlying cause is clear, treatment becomes much more straightforward and is far more likely to be effective.

Below are some of the most common conditions we diagnose and treat at Connolly Dermatology.

Diagnosis and Evaluation

Targeted Testing To Guide Smarter Treatment

At Connolly Dermatology, we focus on confirming the cause before committing you to months of treatment. A thorough evaluation helps us choose the right therapy, set realistic timelines (nails grow slowly), and reduce the likelihood of recurrence.

What Are Your Treatment Options?

Medical and Procedural Care That Supports Real Results

There isn’t one standard plan that works for every case. These concerns develop for different reasons, and growth takes time, so your results depend on both the treatment itself and the environment around the area.

At Connolly Dermatology, we combine targeted medical therapy, in-office care when needed, and prevention strategies that support lasting results. Below is an overview of the most common treatments we use, and how we decide what fits your needs:
