Have you ever had a doctor take a look at this bump? Telling someone what anything is based on a picture is never a good idea- but I did see that you had some photos on your profile. It really looks like nothing to worry about to me. If you are worried, see a doctor- and it sounds like you have some anxiety as well, so it's not a bad idea to talk to your doctor about how you are very anxious about things and have them help you with that as well.
