I have 3 bump(lump?) like things in the back of my head. They don t hurt at all when i put pressure on them. One of them is smaller than the other two. The two others are about 1cm. When i move my finger on them, they kind of move alon a little bit. I also have a sit like thing infront of my ear. It hurts a little bit when i put pressure on it. And it feels like there is something inside of it. More sitlike, but it s huge for a sit, so i don t think it is one. I m kind of scared, so i would like to know if it s dangerous or not. I m 16 and completly healthy every other way. Never been on any other medication , than urin control pills when i was younger.
