I'm 17 years old and recently had a haircut and have just noticed all the bumps and lumps on my skull.

I'm starting to get a bit paranoid and scared now. First I got all worried about a small lump at the back center of my head, which I found out was quite common and part of the skull structure.

Now I have noticed a small lump at the back, right side of my head. I think it's a lymph node. It's not on the other side of my head though, well there might be a smalled one there.

It is in this area - medpics.findlaw.com/imagescooked/14531W.jpg

Just wanted to check there was supposed to be somthing there that's all.

Is this anything to worry about?
