Hello. I recently found a bone on my lower back, like on the pelvis poping out. My right side is sticking out and my left is flat. I m incredibly worried, and I don t know what to do. My big brother was telling me to go for an x-ray . I m still a teen and I really don t want to not to be able to walk anymore. I may be overdramatic, but please, help me. Is this normal, or do I have to do something?
