Firstly, you should not be afraid to tell your parents. They love you the most. I am not a doctor. It could just be a 'heat rash'... my husband gets this when he is hot and working. He uses simple cornstarch to releive it. But it could easily be something else... you may have picked up some germ while swimming or using a public bathroom. Please trust your parents, you may need to see a doctor and get something better than cornstarch. Good luck - Blu
