Nail Fungus (Toenail Onychomycosis)

Understanding the symptoms, causes, and treatment options for fungal toenail infections.

What is Toenail Fungus?

Are your toenails thick, discolored, or brittle? Learn how toenail fungus develops and what treatments can help restore healthy nails.

Toenail fungus, or onychomycosis, is a common infection caused by fungi that thrive in warm, moist environments. It typically begins as a small white or yellow spot under the nail and can spread deeper, causing discoloration, thickening, and nail damage. Early diagnosis and consistent treatment are key to successful recovery.

Common Symptoms

Yellow, white, or brown discoloration of toenails
Thickened, brittle, or crumbly nails
Foul odor or debris buildup under the nail
Separation of the nail from the nail bed (onycholysis)
Pain or discomfort while walking or wearing shoes

When to see a podiatrist

Persistent nail discoloration or thickening
Nails becoming painful, brittle, or deformed
Over-the-counter antifungal products fail to improve symptoms
Infection spreads to other nails or skin
You have diabetes or a weakened immune system

Early detection is important for managing the condition and preventing further complications. Schedule a consultation today.
