I've recently noticed a lump on my neck and I would like a little analysis before I go to my doctor. The lump is touching(But not attached) to the bottom of my jaw line, on my right side. It's about a little smaller than a golf ball, and I've been feeling a little pain/discomfort whenever I maneuver my neck across it(When it gets pinched). I can feel that it is not connected to any muscle, tissue or bone, as I can move it slightly from it's spot. I am an 18-year old male, I'm in fairly good shape physically, and I have no knowledge of any issues like this in my past.
I am going to see my doctor, but since that will take me a couple of days to arrange I would just like an idea of what this may be, and whether I'm making a mountain out of a mole hill.
