One of the most common questions I am asked either in clinic or via our website is some variation of: do I need treatment, or can I manage this myself? It is a sensible question, and the honest answer is that it depends on where you are in the picture.
This article sets out a clear framework for thinking about that decision, covering fungal nail infections and verrucas separately because the considerations differ for each.
Fungal nail infections: prevention or treatment?
When prevention is the right starting point
If you do not currently have a fungal nail infection but you use gyms, swimming pools or communal changing rooms regularly, or if you have had an infection in the past and recovered from it, prevention is absolutely the right focus.
The preventive steps are well evidenced and, frankly, not difficult. Wearing flip-flops in communal wet areas, drying between your toes properly, rotating footwear, keeping nail tools separate, and treating any athlete’s foot promptly. None of these requires a clinic visit, and together they meaningfully reduce your exposure risk.
For athletes, runners and people who spend long periods in enclosed footwear, adding an antifungal shoe spray to the routine and paying particular attention to footwear rotation is a sensible addition.
For people with diabetes, the calculus shifts slightly. Because the consequences of an untreated fungal nail infection are potentially more significant in a diabetic foot, reduced circulation makes healing slower, and a thickened nail can cause pressure damage, routine professional podiatry is worth including even before any infection is visible. Our diabetic footcare guidance covers this in more detail.
When treatment becomes necessary
Treatment is needed when:
- A toenail shows visible yellowing, whitening, browning or a chalky appearance — even at just the tip or one corner
- A nail has thickened noticeably relative to its neighbours
- There is any separation of the nail from the nail bed, even a small amount at the edge
- The nail surface looks dull, rough or crumbly where it was previously smooth
- You have completed a course of home or pharmacy treatment and the infection has not cleared, or has returned
The important principle here is: early is significantly better than late. A small, early infection at the nail tip requires fewer laser sessions and a shorter overall treatment timeline than a fully progressed infection covering most of the nail. Waiting until it is “bad enough to do something about” costs more time, not less.
What about pharmacy treatments?
Over-the-counter antifungal nail lacquers are an appropriate starting point for very early, superficial infections those affecting only the surface layer of the nail near the tip, with no significant thickening or nail-bed involvement. Used consistently and combined with nail filing to thin the nail, they can achieve clearance in these cases.
For infections that have had more time to establish, or where the lacquer has been used for three months or more without clear improvement, a professional assessment is the more productive next step. Laser fungal nail treatment bypasses the penetration problem that limits topical treatments by delivering energy directly through the nail to the infection at the nail bed, and it is the approach we use at We Fix Feet for established or returning infections.
Verrucas: prevention or treatment?
When watchful waiting is reasonable
Verrucas in children and young adults do sometimes clear on their own, as the immune system eventually mounts a response to HPV in that location. This natural clearance can take anywhere from a few months to two years, and there is no reliable way to predict whether it will occur.
Watchful waiting alongside sensible hygiene measures to prevent spread is a reasonable approach when:
- The verruca is a single, small lesion in a child under twelve
- It is not causing significant discomfort during normal activities
- It has been present for less than three months and is not spreading
During this period, the verruca should be covered with a waterproof plaster in communal wet areas to prevent spreading to others and to protect the softened skin from further compromise.
When treatment is the clearer choice
Active treatment rather than waiting is the right decision when:
- The verruca has been present for more than three months without any sign of reducing in size
- There are multiple lesions, or spread to new sites
- It is causing sufficient discomfort to affect normal walking or sport
- The person is an adult or older teenager — natural clearance is less reliable in adults
- You have tried reasonable home treatment (salicylic acid for several months) without improvement
- The affected person has a condition that affects immune function, including diabetes
Home treatments using salicylic acid are the most commonly recommended first-line approach and are appropriate for single, accessible lesions in otherwise healthy people. They work by gradually removing the overlying callus and exposing the infected tissue to the immune system. Their limitation is that they address the surface rather than the viral source within the skin, which is part of why they produce incomplete or temporary clearance in some cases.
For verrucas that have not responded to three to six months of consistent home treatment, or for multiple or painful lesions, K-laser verruca treatment is the approach we use at We Fix Feet. It delivers targeted laser energy to the verruca tissue, provoking an immune response that addresses the viral source rather than just the surface, and it can treat multiple lesions in a single session.
A note on self-diagnosis
One thing worth flagging: both fungal nails and verrucas are commonly misidentified at home. A discoloured nail can be trauma-related rather than fungal. A hard patch on the sole of the foot can be a corn rather than a verruca, and the treatment for each is different. If you are not confident about what you are looking at, a short assessment with a podiatrist will confirm the diagnosis and ensure any treatment you pursue targets the right issue.
Our Knowledge Centre has articles on recognising early signs of both conditions, on why these infections keep returning, and on the costs of laser and verruca treatment at We Fix Feet.
Making the decision
If you are still not sure which category your situation falls into, the simplest approach is to book an assessment. We will review what is there, clearly explain what we are seeing, and provide a recommendation, including whether active treatment is needed right now or a preventive approach is sufficient for your situation.

Frequently Asked Questions
Is it possible to prevent fungal nail infection entirely? Consistently applying the key preventive habits protective footwear in communal spaces, proper foot drying, footwear rotation, and treating athlete’s foot promptly significantly reduces risk. No prevention strategy eliminates risk entirely, but it makes the odds meaningfully lower.
Can I treat a verruca and a fungal nail at the same time? Yes. Both conditions can be assessed and treated at We Fix Feet. Where a person has both conditions, we will assess each separately and outline a plan that addresses both.
Should children have verrucas treated or leave them to clear up naturally? For a single, small, non-painful verruca in a child, watchful waiting is reasonable. For multiple verrucas, painful or spreading lesions, or a verruca present for more than three to six months without any sign of reducing, active treatment is the better approach. A podiatrist can help you make that call based on what the verruca actually looks like.
How do I know if my home treatment for a fungal nail is working? The first visible sign is typically a small area of healthier-looking new nail growing from the base. This may not be visible for three to four months even with effective treatment, because toenails grow slowly. If there is no sign of new, healthy growth at the base after four months of consistent treatment, it is worth having the nail professionally assessed.
