Two of my three kids have had it... I too looked at the websites and it scared me! Luckily Maddie had maybe 4 or 5 'bumps' on her arm, and Ben had a cluster of 3 on his belly and that was all the more they got. It took them both about 6 months for their bodies to figure out how to fight the virus and get rid of them. They looked the nastiest at the very end, for the most part they were little white wart like bumps, then at the end they got fiery red and irritated looking. Ben's JUST went away this month!
Our doctor said it was a self limiting virus and you could treat it, but it probably wouldn't help them go away any quicker. I think one thing he mentioned was digging out the 'core' - he said it does help sometimes, but is painful. We opted to leave it alone since it was so mild.
A friend who is into homeopathic approaches suggested increasing the kid's l-lysine (sp??) because it boosts their immune system and would help them fight the virus (didn't really do this!) and tea tree oil. The tea tree oil smells like eucalyptus which isn't all that pleasant, but it is antiseptic and it seemed to dry the bumps out, especially at the end. If nothing else they won't get infected. We did use the oil towards the end when they looked nasty. Not sure what would have happened had we started with it sooner.
