A verruca is a type of wart that commonly occurs on the soles of the feet or around the toe area and is caused by the Human Papilloma virus (HPV). A single verruca can grow up to a diameter of half an inch (~1.25cm). These warts are contagious and sit just underneath the top layer of skin, meaning it often does not automatically trigger the immune response of the body. The virus enters the body through small breaks in the skin, often too small to see with the naked eye. The virus survives well in humid and damp environments, so is often contracted in public places such as swimming pools.
A verruca can look very similar to a corn and vice versa. Whilst it may not be obvious just by looking at it, there is usually a difference in feeling between a corn and verruca. Typically, a verruca is painful when it is pinched but not when it is pressed, and a corn is painful when it is pressed but not when pinched. This is not definitive, so it’s best to get it checked out before applying any products.
There is also a possibility that what looks like an abnormal verruca can be a form of skin cancer. This is why it is important to see a professional if you’re unsure so that it can be examined and you can be signposted to the relevant services where necessary.
What can a verruca do?
Other than being stubborn to get rid of, verrucae can also cause a number of other issues. The verruca can cause pain from the overgrowth and hardening of the skin in the specific area affected. This can become painful as it will put pressure on the skin around the area and underneath, meaning people tend to avoid putting weight on it to reduce discomfort.
This can then result in an altered posture and gait, which can lead to pain in the joints and muscles further up the chain, particularly in the legs and back. Friction from walking and footwear can aggravate a verruca, leading to further pain and discomfort, especially if verruca is on a weight bearing part of the foot.
So, what can I do?
There are a number of methods for treating a verruca, one of which is simply leaving it alone. In children, 66% of verrucae disappear on their own within 2 years, but for adults it can be much longer. We would recommend seeing a podiatrist if it is painful or uncomfortable and affecting your daily activities.
Debridement is one form of treatment to help remove the overlying hard skin of a verruca and reduce any pain. ‘Over the counter’ treatments from your local pharmacy can sometimes be suitable. Swift Microwave therapy sends a microwave pulse through the verruca, and is the most effective treatment for verruca on the market with a success rate of 93% following 3 treatments. Faulknor’s needling is an alternative we recommend if Swift is not suitable.
If one or more verrucae is causing you pain or discomfort, or has been there for a number of years, we would recommend seeing a podiatrist. They will be able to diagnose whether it is definitely a verruca as well as recommend and apply an appropriate treatment plan.
