If you've frozen it, filed it, taped it and covered it in salicylic acid and it's still there, you're not doing anything wrong — verrucas are genuinely stubborn. Here's what's going on, and how a podiatrist thinks about clearing one.
Why verrucas linger for months
A verruca is a wart on the sole of the foot caused by the human papillomavirus (HPV). The virus lives in the upper layers of skin and is good at staying under your immune system's radar — which is exactly why it can sit there for months or even years.
Two things make feet especially tricky. First, the skin on the sole is thick, so treatments struggle to reach the virus. Second, walking presses the verruca inward, so it can flatten and spread sideways rather than clearing.
What the evidence actually says
Most verrucas will clear on their own eventually as your immune system catches up — but that can take a long time, and painful ones are hard to ignore. Salicylic acid needs consistent use over weeks; clinical freezing is stronger than pharmacy sprays but can be uncomfortable; and most home remedies are thin on evidence.
Where Swift microwave therapy fits in
For verrucas that have resisted everything else, we offer Swift microwave therapy at our Battersea clinic. It delivers precisely controlled microwave energy to prompt your immune system to respond. It's non-surgical with minimal downtime.
When to see a podiatrist
Book an assessment if your verruca is painful, spreading, or hasn't shifted after a few months of home treatment. If you have diabetes or reduced circulation, please don't self-treat — see a podiatrist first.
We'll confirm the diagnosis and set out the options that suit you. No GP referral needed.
