question: My name is danielle and I am 23 years old and I have this bump on my breat bone since I was 14/15. I went to different doctors to figure out what it actually was. The last doctor I saw about this told me and my mother it was just overgrown cartilage. But it has grown bigger over the years and the pain is severe at times. My ribcage at times feels like its being restricted. I can not even wear a bra because it is uncomfortable. I have recently been told on a separate matter that I have lipoma. And I have a vitamin D deficiency. I also have very high cholesterol,but that is because of genetics. Please please tell me what I can do. Thank you.
