Early Signs of Fungal Nail and Verruca You Should Not Ignore
Most people who arrive in clinic with an established fungal nail infection or a cluster of verrucas will tell me the same thing: they noticed something months ago, were not sure what it was, and decided to wait and see.
That is entirely understandable. Both conditions can look unremarkable in their early stages, and it is easy to put them to the back of your mind.
The difficulty is that neither fungal nails nor verrucas tend to resolve on their own as people hope, and both respond considerably better to treatment at an early stage than at a later one.
Here is what to look for in your own feet, and in your children's.
Early signs of a fungal nail infection
A fungal nail infection typically starts at the tip or edge of the nail and works inward.
In the early stages, it may be subtle enough to dismiss — a faint yellowing that could be mistaken for nail varnish staining, or a very slight thickening that just makes the nail feel a little heavier than normal.
Specific things to look for:
Colour change
Yellow is most common, but white, brown or a greyish tint can all indicate infection. It often starts at one corner of the nail rather than across the whole surface.
Change in texture
The nail surface may look duller than the others, or slightly rougher. A chalky or powdery appearance at the tip is a common early sign.
Slight thickening
Healthy toenails are relatively flat. An infected nail often starts to thicken subtly at the tip, and later more significantly as the infection progresses inward.
The nail edge lifting slightly
If a small amount of the nail has separated from the nail bed, even just at the corner, that is worth getting looked at.
At the very early stages, one or two signs may be present rather than all of them. If you notice something but are not sure whether it is an infection or natural variation, a podiatrist can help clarify what you are looking at.
Early signs of a verruca
Verrucas are caused by HPV and appear on the weight-bearing surfaces of the foot, typically the heel, the ball of the foot or under the toes.
They do not always cause pain, so they can remain for some time before a person notices them.
Specific things to look for:
A small hard patch of skin
This can look different from a callus, which tends to be more diffuse and uniform. A verruca is usually a discrete, well-defined patch.
Tiny dark spots in the centre
These are small blood vessels within the lesion. They can look like black or dark red pinpricks and are among the most useful distinguishing features.
Pain on pressure or sideways pinching
A callus tends to be sore when pressed directly. A verruca is often more painful when pinched from the sides.
Interruption to the skin lines
The natural skin lines on the sole of the foot normally flow continuously. A verruca can disrupt this pattern, with the lines running up to the edge of the lesion rather than through it.
Things that may suggest a verruca
- A discrete hard patch rather than widespread hard skin.
- Small black or dark-red pinprick marks.
- Discomfort when the area is pinched from the sides.
- Natural skin lines appearing interrupted around the lesion.
Checking children's feet
In children, verrucas are extremely common following school swimming lessons and can appear quickly after exposure in a communal changing room. If your child is complaining of a sore patch on the sole of their foot, it is worth checking rather than assuming it is simply a blister.
Why early treatment makes a difference
The difference between treating a verruca that has been present for three months and one that has been present for two years is significant.
The longer a verruca has been established, the more the local immune environment has adapted around it, which tends to mean a longer treatment course and more sessions.
With fungal nails, an infection that occupies a small portion of the nail near the tip can often be cleared in fewer laser sessions than one that has progressed to cover most of the nail bed.
Less established
A smaller area is affected and there is less established infection for treatment to address.
More established
The condition may have had more time to spread or become persistent, potentially creating a longer treatment pathway.
Earlier means less work for the treatment to do and, with fungal nails, a shorter overall timeline before a clearer nail grows through.
