Verrucae grow on your skin, like a cold, they spread from one person to another.

They can grow on any part of your foot.

They are not dangerous and if you leave them alone they will go away by themselves but this can take a long time.

If they hurt a lot go and see a doctor, nurse or chiropodist.

But,
IF THEY DON'T BOTHER YOU, DON'T BOTHER THEM!
