Nail fungus (onychomycosis) is a common condition that occurs when fungi infect your fingernails or toenails, often starting as a white or yellow spot under the tip of your nail. As the infection progresses, the fungus can cause discoloration, thickening, crumbling, and even detachment of the nail.
Fungal infections typically develop in warm, moist environments and are more common in toenails than fingernails due to increased exposure in sweaty shoes and socks. Without treatment, the infection can spread to other nails or surrounding skin.
Nail fungus can cause visible and sometimes painful symptoms, including:
Yellow, brown, or white discoloration
Thickened or brittle nails
Crumbly or ragged edges
Nail distortion or shape changes
Separation of the nail from the nail bed
Mild odor coming from the affected nail
If left untreated, the infection can worsen and become harder to treat. In severe cases, it may even lead to permanent nail damage or secondary bacterial infections.
Toetal Podiatry uses advanced in-office diagnostic tools, including microscopy and lab tests, to confirm fungal infections and determine the best course of treatment.
Symptoms may develop slowly and include:
Yellow, white, or brown discoloration of the nail
Thickened or misshapen nails
Brittle, crumbly, or ragged edges
Foul odor from the nail
Nail lifting off the nail bed (onycholysis)
Itching or redness around the nail
As the infection progresses, nails may become painful and difficult to trim, sometimes making walking uncomfortable.
Toetal Podiatry offers in-office diagnostic tools to confirm fungal infections, such as:
Nail scrapings for lab analysis
Microscopic examination or fungal culture
Nail biopsy in rare cases to rule out psoriasis or trauma
Early diagnosis ensures faster and more effective treatment.
Yes. Even after successful treatment, reinfection is common if preventive measures aren’t taken. You can reduce recurrence by:
Keeping feet clean and dry
Wearing breathable shoes and moisture-wicking socks
Avoiding barefoot walking in shared areas
Regularly disinfecting shoes and nail tools
Not sharing clippers or nail polish
Getting routine foot checks with your podiatrist
Q: Is nail fungus painful?
A: It usually starts without pain, but thickened or distorted nails can become uncomfortable or cause pressure in shoes over time.
Q: Can I wear nail polish with a fungal infection?
A: It’s not recommended — polish can trap moisture and make the infection worse. Medicated polishes are a better alternative.
Q: How long does treatment take?
A: Nail fungus is slow to heal — it can take 3–6 months or longer to see full results, as new healthy nail grows in.
Q: Will the nail go back to normal?
A: Often yes, but in some severe or long-term cases, nail shape may remain altered even after clearing the fungus.
EXCELLENT Based on 82 reviews Olivia T2025-08-21Trustindex verifies that the original source of the review is Google. Dr. Erfanian was thorough, personable, and very clear about the steps he was taking/the follow up for my procedure - I couldn’t recommend him more! Steph Arizona2025-08-11Trustindex verifies that the original source of the review is Google. Thank you so much for such a top tier service. The doctors and staff are so friendly and supportive. I was able to get an appointment with two hours of calling and I really needed the appointment. Thank you doctor J. Erianian for providing a high quality service for patients! I would recommend this doctors office especially on short notice! Nazy Farkhondeh2025-07-08Trustindex verifies that the original source of the review is Google. Dr. Sharaara Rahman is such a breath of fresh air!!! Being a runner training for a marathon—aches, pains, tenderness are a cause for SO much anxiety. It's so hard to get proper diagnosis and care. It's always—"well it could be this" or "it's possible this is causing but maybe not" and the solution is always just RICE (rest, ice, compression, elevation). Ok, I get that, but that's not a real solution. Dr. Sha was patient, kind, funny, and assured me she going to be my partner in getting me through the race. She was so thorough in her analysis of what was going on and presented thoughtful and simple solutions - all while being super transparent about pricing and not pushing me in any direction. It's so rare to walk in an anxious athlete and walk out immediately feeling confident that you're on the right path. I cannot thank her enough! Varduhi Melikyan2025-07-03Trustindex verifies that the original source of the review is Google. I recently visited Dr. Vera Melazhnik at Madison office and had a positive experience. Doctor was professional, attentive, and took the time to listen to my concerns without rushing through the appointment. She asked thoughtful questions, explained things clearly, and provided a plan for next steps that made sense and felt personalized. I can highly recommend Dr. Melazhnik. Crienna Cronly2025-07-03Trustindex verifies that the original source of the review is Google. I very much recommend Dr Rahman, who has been treating me for a foot issue of late. She is warm, caring, knowledgeable and efficient. The assistants and front desk staff have all been great and friendly. Dr Malezhik treated me for a different issue at another clinic and I highly recommend her as well. Mahi Joshi2025-06-25Trustindex verifies that the original source of the review is Google. Dr Rahman truly cares about her patients and handles them with the utmost expertise. I’ve been to her twice now and both times have been very satisfied with the level of care I’ve received Liana Sargsyan2025-06-19Trustindex verifies that the original source of the review is Google. I took my daughter who is a dancer, she got injured during the rehearsal. We saw Dr. Malezhik, she was absolutely amazing, very patient and kind. We went back for a follow up appointment and had the best experience. The entire staff was very warm and welcoming! I recommend Toetal podiatry! Joseph Herbst Music2025-06-11Trustindex verifies that the original source of the review is Google. Dr. Rahman made me feel very comfortable and confident in her work as I dealt with two toe infections. Every appointment was always timely, and I always left feeling good about the way my feet were healing. She always made it very clear what I should be doing at home to care for them, as well as what our next steps would be depending on how they looked. I’d highly recommend her!
