Hi, i m 13 years old and there has been thing purple bump/spot on the right side of my head. We noticed it in December and we thought I may have hit my head so we let it go. Well It still never went away and i m scared to tell my family. I have some symptoms of a brain tumor like bad migraines, dizziness , and behavior changes. I m nervous to get it checked out. Do you have any clue on what it can be?
