Not necessarily! Not all adverse nail symptoms means a fungus is present. Nails can change over time due to past injury to the nail plate such as dropping an item on or stubbing the toe on a piece of furniture. This may result in abnormal growth, something our doctors refer to as "dystrophic" nails which can commonly be mistaken with fungal infections - they can look very similar.

The best way to determine the nature of your problematic nail(s) is by having a nail biopsy performed, meaning our doctors simply trim a small sample of your nail and have it tested by a laboratory to diagnose either a presence of fungus or simply a previously injured nail.  Dystrophic nails are best treated with solutions that can reduce nail thickness and color changes rather than an anti-fungal topical.
