Hello. I have discovered a strange addition to one of my five year old sons toes (right foot, the one next to his big toe) On the right of his toe is a large roundish lump which sticks out quite a lot, it also seems to have damaged part of where the nail should be. I haven’t experienced verrucas before but is that what it is likely to be? He says it hurts and doesn’t like me touching it. Thank you for any advice!
