Hi H.,
My 5 yr old boy has had it since February. He started with one on his foot and two on his chest. We treated the foot thing and its gone so now we are treating the chest one. We just use compound W. Now I just saw a small on on his back last week. They only hurt him when we put on he Compound W.
We don't know where he picked his up. We got to Misawa Jp in September.
Sorry I don't have better help
