First, know that you are not alone- many people have questions about things similar to this and have no idea what is going on. Don't be afraid to ask your parents to take you to the doctor- I know it's uncomfortable to talk about things of this nature with parents sometimes, but it's much better to get a doctor to examine you and have that peace of mind. In the meantime, you can keep an eye on the spot to notice any changes- but don't over examine the area- you will start seeing things that aren't there and maybe even irritate other areas by pulling on them. Keep the area clean and talk to your parents about getting an appointment with a doc. Let us know how you are doing!
