I'm a 15 year old girl and I have a lump under my left breast. I guess it's about where the wire in a bra is. There is a tiny red dot on my skin above the lump (lump is under skin, its right on top of my rib). I do not know if they are related, but I also have a bump right below my tail bone, but it's a lot harder, and I have a tiny bump on the outside of my vagina (closer to the very inside of my thigh). I've had them for a few weeks now but i'm starting to get scared because they arent going away. Please help me!
