Hello! I'm 25 and noticed a hard lump on my neck just at the angle of my jaw. It is easier to feel when I turn my head towards the right (it's on the left). It doesn't move when I push it.
It's been there for about 6 months now and grown slightly bigger, it doesn't hurt at all. Because it doesn't hurt and was small I kind of forgot about it. 
now it's grown and is more prominent I'm quite worried. 
Has anyone had anything similar and is this something I should be getting checked out asap?
