Hi! I think it can happen and probably more than you think because we do quite a bit of sweating there. I am sure this happens to many people. Keep your hands off of it though and just wash it. Our hands have a lot of bacteria on them and it can transfer and make things worse. If it doesn't clear up, see your doctor. Sometimes infections need antibiotics. If you are unsure, then I'd see your doctor right now. But I wouldn't be worried that it is dangerous or be super freaked out by it. :>))
