Bumps and Lumps

So I have this bump on the right side of my neck. Right on the curve where my neck meets my shoulder. I made a doctors appointment to get it checked out since I've had it for about a month now and although it's not growing (or at least I haven't noticed if it's growing) it does feel tender to the touch. I did a little research and it could just be a small cyst or something gross like that but I'd feel more comfortable knowing what it is and I don't really want it there no matter what it is...so I'll see if there's something that can be done either way.
