I have this lump inside my neck on the lower right side and its been there for about a year. A few years ago I had something similer but on the other side and it went away. It causes me no pain but it feels like its getting bigger. I had it looked at during my last physical and was told it was just a cyst.  I also have a bump on the back of  my head close to my hairline at the bottom. Its about the size of a penny and very hard. Ever since I discovered it a few weeks ago it has only gotten bigger and now it is very sensitive.I am a very healthy and fit teenage girl who is 5 7. Please any information would be helpful!
