My son is 11 soon to be 12. About 4 months ago he developed a patch of bumps on his face that at first I thought was just acne developing because of his age. The bumps are hard, small and white and can not be popped. I took him to his regular doctor and she said that they were a type of wart that would go away in a few months. Since then a couple of them have been scraped off during rough play and bled when they did. Just in the last 2 weeks he has developed more on other areas of his body. About a dozen on his back, a handful on his chest and 1 or 2 on his leg. Any ideas? Any suggestions for treatment?
