Causes And Symptoms
Plantar warts or verrucae are caused by an infection of the outer layer of the skin by the HPV virus. Plantar warts typically not cancerous, they are caused by a non-malignant strain of the HPV virus. There are over 100 types of HPV virus and only a few of them causes warts on the foot. The infection causes the skin to overgrow and thicken, leading to a benign (non-cancerous) skin growth, which appear as a wart.
Warts are more likely to develop if you have the following risk factors
- Children and teenagers
- People with weakened immune systems
- People who have had plantar warts before
- People who walk barefoot in common environment such as such as bathrooms, changing room of gyms and swimming pools
Typically, plantar warts appear to be rough, sometimes raised area of the skin, typically with tiny ‘dots’ visible at the centre. They can be extremely painful while walking or standing.
Signs and symptoms of plantar warts include
- A small, fleshy, rough growth on the bottom of your foot, usually the base of the toes and ball of the foot or heel
- Hard, thickened skin (callus) over a well-defined “spot” on the skin
- Appearance of ‘Black dots’, which are commonly called wart seeds but are actually small, clotted blood vessels
- Normal lines and ridges in the skin of your foot are interrupted
- Pain or tenderness when walking or standing
When Should You See A Podiatrist
Most plantar warts clear with time and can be left untreated without causing any problems. Sometimes, it is difficult to tell a plantar wart (viral infection) from a corn (hard skin) It is highly recommended to seek expert advice from a Podiatrist if your wart becomes painful on weightbearing or you notice a ‘spread’. You should not attempt to self-treat, especially if you are an elderly, have diabetes or a weakened immune system as this may increase the risk of infection.
