See a physician?

I did, but I think they made it worse :(

What exactly have you tried ? I personally prefer to do things without a lot of chemicals or pharmaceuticals or medicines. I found this but of course up to you how you decide to treat the wart . http://wholenewmom.com/health-concerns/the-easiest-and-cheapest-natural-wart-treatment/ If nothing else it is worth giving it a read. Hope you find what you are looking for .

Someone making money by selling a book on "urine therapy" would not be my go-to person for advice on treating a child's health problem (aside from this "therapy" being ridiculous, the writer is way off on how to tell apart warts and calluses).

If I am dissatisfied with a physician's treatment of a commonplace and highly treatable problem, my next move is to find a better physician - not turn to woo. That's even more important when you're dealing with a child who has no choice in the matter.

I would try tea tree oil.
